“ Such men say they can not make enough manure on the farm and are too poor to buy. Why not, then, commence plowing under green crops, the only manure within easy reach? If fifty acres can not be turned under the first year, put at least one acre under, which will help feed the rest. Why be contented with thirty bushels of corn per acre, when eighty or one hundred may be had? Why raise eight or twelve bushels of wheat per acre, when forty may as well be had? Why cut but one half-ton of hay per acre, when the laws of nature allow at least three? ”

“ Besides, manuring with green crops is not transitory in its effects; the land remembers the generous treatment for many years, and if at times lime or ashes be added to assist decomposition, will continue to yield remunerative crops long after land but once treated with stable manure or guano fails to produce any thing but weeds. The skinning process, the taking off of every thing grown on the soil and returning nothing to it, is ruinous alike to farm and farmer. Thousands of acres can be found in various parts of the country too poor to pay for cultivating without manuring. ”

“ Much is gained by changing seed. No two varieties are made up of the same constituents exactly in the same proportion; hence, a soil may be exhausted for the best development of one, and still be fitted to meet the demands of another. Even when the same variety is desired, experience shows the great benefit of planting seed grown on a different soil. The best and most extensive growers procure new seed every two or three years, and many insist on changing seed every year; and undoubtedly the crop is often doubled by the practice. ”

“ It is a strong, vigorous grower; and one peculiarity of it is, that insects will not attack vines of this variety if other kinds are within reach.
Planted on extremely poor ground, it will, perhaps, yield more bushels of tubers, and those of better quality, than any other variety that could be planted on the same soil. Among all the old or new sorts, perhaps, no potato can be found that deteriorates so little in quality from maturity to maturity again. And, in fine, where only high quality with moderate yield are desired, it has few if any superiors. ”

“ The characteristics of a potato, such as quality, productiveness, healthfulness, uniformity of size, etc., depend much on the nature of the soil on which it originated. These characteristics, some or all, imbibed by the minute potato from the ingredients of the soil, at its first growth from the seed of the potato-ball, adhere with great tenacity to it through all its generations. A seedling may, in size, color, and form resemble its parent ”

“ It costs no more to cultivate an acre of rich, productive land than an acre of poor, unproductive land; and the pleasure and profit of harvesting a crop that abundantly rewards the husbandman for his care and labor are so overwhelmingly in favor of rich land as to need no comment. ”

“ In no argillaceous soil can the potato be grown to perfection as regards quality. Large crops on such soil may be obtained in favorable seasons, but the tubers are invariably coarse-fleshed and ill-flavored. To produce roots of the best quality, the ground must be dry, deep, and porous; and it should be remembered that, to obtain very large crops, it is almost impossible to get too much humus in the soil. Humus is usually added to arable land either by plowing under green crops, such as clover, buckwheat, peas, etc., or by drawing and working in muck obtained from swamps and low places. ”

“ Raw potatoes, fed occasionally and in small quantities, are a good tonic for stock of any kind which is kept principally on hay; but all experiments show that when the potato is used for fattening purposes, the tubers should in some way be cooked, that the animal to which they are fed may derive from them the greatest possible amount of nutriment. Repeated experiments demonstrate the fact that horned cattle or hogs lay on as much fat from the consumption of two thirds of a given quantity of potatoes properly cooked as they will by eating the entire quantity in a raw state. ”

“ Many growers argue that potatoes should be planted whole. The only plausible theory in support of whole seed is, that the few eyes that do start have a greater supply of starch available from which to obtain nutriment until the plant can draw support from the soil and atmosphere. But experiments also demonstrate that if all the eyes except one or two near the middle be cut out of the seed-potato, such seed will push with the greatest possible vigor. ”

“ Experience proves that no better method can be adopted to bring up lands partially exhausted, which are remote from cities, than plowing under green crops. By this plan the farmer can take lot after lot, and soon bring all up to a high state of fertility. True, he gathers no crop for one year, but the outlay is little; and if in the second year he gathers as much from one acre as he formerly did from three, he is still largely the gainer. ”

“ Ozone, supposed to be a peculiar form of oxygen, is exhaled from every part of the green surface of plants in health, and effectually repels the attacks of mildew; but it is found that when the atmosphere is very dry, or, on the other hand, very humid, plants cease to evolve ozone, and are therefore unprotected. Winds from the ocean are strongly ozonic, and it is ascertained that plants growing on soil to which salt has been applied evolve more ozone than others. Hence the benefit derived from the use of salt on potato lands. ”

“ It is traceable mainly to poverty of the soil in certain ingredients imperatively needed by the crop for its best development, and to the pernicious effect of enriching with nitrogenous manures. Any one who will plant on suitably dry soil, enriched only with forest-leaves, sea-weeds, or [Pg 4] by plowing under green crops until the whole soil to a proper depth is completely filled with vegetable matter, will find to his satisfaction that the potato can yet be grown in all its pristine vigor and productiveness. ”

“ Leaves from the woods, buckwheat straw, bean, pea, and hop vines, etc., plowed under long enough before planting to allow them time to rot, are very beneficial. Sea-weed, when bountifully applied, and turned under early in the fall, has no superior as a manure for the potato. No stable or barn-yard manure should be applied to this crop. If such nitrogenous manure must be used on the soil, it is better to apply it to some other crop, to be followed the succeeding year by potatoes. The use of stable manure predisposes the tubers to rot ”

“ The intelligent farmer, who grows large crops for market, will always so arrange as to have a clover-sod on dry land in high condition each year for potatoes. It is said by many, in regard to swine, that "the breed is in the trough;" though this is certainly untrue to a certain extent, yet it is undeniable that in potato-growing success or failure is in the character of soil chosen for their production. ”

“ One peculiarity of this potato is, the largest tubers appear to be of as good quality as the small ones. With proper soil and culture, it yields a fair crop; is quite free from disease; and its smoothness, high flavor, and fine appearance make it much sought after in the market.
The Fluke, a very late potato, is a great favorite with many who produce for market. Its yield is very large; and its smoothness and uniformity of size make it altogether a desirable variety. It is generally free from disease. In quality it is rather above medium. ”

“ Why clover, or clover and buckwheat lands, are so strongly urged is, such lands have in them just what the tubers need for their best and healthiest development; the soil is rendered so rich, light, and porous, and so free from weeds, that the cultivation of such land is rather a pleasure than otherwise, and at the close of the season the tangible profits in dollars and cents are highly gratifying. ”

“ The gray and black markings, however, of the wings differ perceptibly in the two species; and in the tobacco-worm moth there is always a more or less faint white spat, or a dot, near the centre of the front wing, which is never met with in the other species. The potato-worm often feeds on the leaves of the tobacco plant in the Northern States. In the Southern States, in Mexico and the West-Indies, the true potato-worm is unknown, and it is the tobacco-worm that the tobacco-grower has to fight. The potato-worm, however, is never known to injure the potato crop to any serious extent. ”

“ This insect, in common with our other blister-beetles, has the same properties as the imported Spanish fly, and any of them will raise just as good a blister as that does, and are equally poisonous when taken internally in large doses. Where the striped blister-beetle is numerous, it is a great pest and very destructive to the potato crop. It eats the leaves so full of holes that the plant finally dies from loss of sap and the want of sufficient leaves to elaborate its juices. In some places they are driven off the plants (with bushes) on a pile of hay or straw, and burned. ”

“ Several cannibal and one parasitic insect are known to prey upon the larva of the Colorado potato-bug, and the eggs in vast numbers are eaten by several species of lady-birds and their larva.
GENERAL REMARKS ON INSECTS.
The time is not far distant when the American farmer will be obliged to put forth greater efforts to destroy noxious insects than he has hitherto. It is a well-known fact that noxious insects are increasing in a rapid rate throughout every part of our land. The country is becoming so "buggy" that eternal vigilance is the price of every thing produced from the soil. ”

“ Just before the last hoeing, sprinkle on and around the hill a large handful of wood-ashes, or an equal quantity of lime slacked in brine as strong as salt will make it.
But for the generality of farmers, those who grow only their own supply, or those who produce largely for market, no other method of preparing the soil is so good, so easy, and so cheap as the following; it requires time, but pays a big interest: Seed down the ground to clover with wheat or oats. As soon as the grain is off, sow one hundred and fifty pounds of plaster (gypsum) per acre, and keep off all stock. ”

“ If the last plowing be deferred until the vines are large, a large proportion of small potatoes is sure to be the consequence. After a certain stage of growth, new tubers are formed each time the soil is disturbed; these never fully develop, they rob those first formed, and make the crop much inferior to what it should be. By the mode of culture described, the ground is made warm and mellow close up to the seed-potatoes, the roots soon fill the whole hill, and tubers are formed that have nothing to do but to grow. The writer is aware flat culture has strong advocates ”

“ The larva subsequently hatches out, and bores into the heart of the stalk, always proceeding downward toward the root. When full grown, it is a little more than one fourth of an inch in length, and is a soft, whitish, legless grub, with a scaly head. Hence it can always be readily distinguished from the larva of the stalk-borer, which has invariably sixteen legs, no matter how small it may be. Unlike this last insect, it becomes a pupa in the interior of the potato-stalk which it inhabits: and it comes out in the beetle state about the last of August or beginning of September. ”

“ The stalk inhabited by the larva wilts and dies. The perfect beetle, like many other snout-beetles, must of course live through the winter, to reproduce its species the following spring. In Southern Pennsylvania, some years, nearly every stalk of extensive fields is infested by this insect, causing the premature decay of the vines, and giving them the appearance of having been scalded. In some districts of Illinois, the potato crop has, in some seasons, been utterly ruined by this snout-beetle, many vines having a dozen larvæ in them. This insect attacks no plant but the potato. ”

“ Thus grown, potatoes are of inferior quality, and the yield is not always satisfactory. Flavor, however, is seldom thought of by the hungry denizens of our cities, in their eagerness to get a taste of something fresh.
Market gardeners will find great benefit from the use of wood-ashes, lime, and the phosphates. Sprinkle superphosphate in the hill at the rate of two hundred pounds per acre; mix it slightly in the soil with an iron rake or potato-hook, then plant the seed. ”

“ The perfect beetle appears about ten to fourteen days after the pupa is formed, begins to pair in about seven days, and on the fourteenth day begins to deposit her eggs. There are three broods of this insect every year. Neither geese, ducks, turkeys, nor barn-yard fowl will touch the larva of the Colorado potato-bug when it is offered to them, and there are numerous authentic cases on record where persons who have scalded to death quantities of these larvæ, and inhaled the fumes of their bodies, have been taken seriously ill, and even been confined to their beds for many days in consequence. ”

“ Thus three crops are put under within a year, the ground is left strong, light, porous, free from weeds, ready to grow a large crop of potatoes, or almost any thing else.
Much is gained every way by having and keeping land in a high state of fertility. Some crops require so long a season for growth, that high condition of soil is absolutely necessary to carry them through to maturity in time to escape autumnal frosts. In the Western States manure has hitherto been considered of but little value. ”

“ Hybrids, with very few exceptions, are sterile, they fail to propagate themselves from seed, and must, to preserve them, be propagated by grafts, layers, or suckers. No change is perceptible in the fruit produced from blossoms upon which the operation of cross-breeding or hybridizing has been performed; but the seed of fruits so obtained may be planted with the certainty of producing a fruit or tuber commingling the qualities, colors, and main characteristics of both parents. ”

“ On rather poor, sandy soil, manured in the hill with wood-ashes, common salt, and plaster only, it will produce in ordinary seasons two hundred bushels per acre of sound, merchantable tubers, that will always command the highest market price. Any potato cultivated for a long series of years will gradually become finer in texture and better in quality; but its liability to disease will also be greatly increased. ”

“ It is asserted by some authors that the black blister-beetle is injurious to the potato; but I can not see how it could do much damage to that crop, as the perfect insect does not appear until late in August, when the potato crop is nearly out of its reach. Not so, however, with the black-rat blister-beetle, which is on hand ready for business early in the season. This insect does considerable damage to the potato in Iowa, and neighboring States; it is also found, though in not so great numbers, throughout the whole of the Northern States. ”

“ In treating for the potato-rot, "an ounce of prevention is worth a pound of cure;" for when leaves or vines are once dead, they ever remain so. All that can be done for potatoes infested is to stop the mildew from spreading, by destroying it where it is, and by strengthening "those things which remain." The writer was led to the adoption of the remedy proposed by experiments made upon fruits. ”

“ If all cultivators would act in concert and with a will, insects might be reduced in numbers very rapidly. Most moths of night-flying insects are attracted to and destroyed by small bonfires kindled in still evenings during the summer months.
Bottles half-filled with sweetened water, hung here and there, will trap countless bugs. Strong soap-suds applied immediately after they hatch is a sure remedy for plant lice. Molasses and water, to which a little arsenic has been added, placed in shallow dishes among the vines, is good medicine for potato-bugs, and all bugs in general. ”

“ In plants with perfect flower, the stamens are generally situated around and above the pistil, so that the pollen falls upon the stigma by mere force of gravity. In the potato, the pollen is conveyed from the anthers to the stigma by actual contact of the two organs.
Cross-breeding in plants consists in fertilizing one variety with the pollen of another variety of the same species. The offspring is called a cross-breed, or variety. ”

“ Market gardeners, many of whom from necessity plant on the same ground year after year, often use fine old stable manure with profit. Usually they plant only the earlier varieties, crowd them with all possible speed, dig early, and sell large and little before they have time to rot, thus clearing the ground for later-growing vegetables. ”

“ There are those who argue that manure is never necessary—that plant-food is supplied in abundance by the atmosphere; it was also once said a certain man had taught his horse to live without eating; but it so happened that just as he got the animal perfectly schooled, it died. ”
