Worms

“ The worms carry into their homes leaves and stalks to eat. They bring out, and throw away, things which they do not like. Worms show much sense in the way in which they carry things in and out of their holes. If a stem will not go in, they turn it over, and try it in some other way.
Mr. Worm at Home.
Worms usually come out of their holes at night or in wet weather. If they go far from their house, they cannot find their way back. Then they make a new hole. Each worm lives alone. ”

“ Some Men are of Opinion, that these Worms breed in the Plank; but I am perswaded they breed in the Sea: For I have seen Millions of them swimming in the Water, particularly in the Bay of Panama; for there Captain Davis, Captain Swan and my self, and most of our Men, did take notice of them divers times, which was the reason of our Cleaning so often while we were there: and these were the largest Worms that I did ever see. I have also seen them in Virginia, and in the Bay of Campeachy; in the latter of which places the Worms eat prodigiously. ”

“ Perhaps you may have observed an enthusiastic fisherman in pursuit of worms? The day is always warm, and his performance upon the shovel conduces to profuse perspiration. He seems never to strike precisely the spot where the worms frolic. He labors with tremendous energy until he has excavated a couple of cellars and a rifle-pit, from which he rescues but two or three worms, while all around him the earth is perforated with holes, into which other vermicular creatures are perceived to disappear before he can lay his hands on them. ”

“ Worms also prepare the ground in an excellent manner for plant life, periodically exposing the mould to the air, sifting it so that no stones larger than the particles they can swallow are left in it, mingling the whole intimately together, burying all decaying objects within reach of the roots of the plants, allowing air to penetrate deeply into the earth. “When we behold a wide, turf-covered expanse, we should remember that its smoothness, on which so much of its beauty depends, is mainly due to all the inequalities having been slowly levelled by worms. ”

“ Morren states [14] that worms often lie for hours almost motionless close beneath the mouths of their burrows. I have occasionally noticed the same fact with worms kept in pots in the house; so that by looking down into their burrows, their heads could just be seen. If the ejected earth or rubbish over the burrows be suddenly removed, the end of the worm’s body may very often be seen rapidly retreating. This habit of lying near the surface leads to their destruction to an immense extent. ”

“ Nor should we forget, in considering the power which worms exert in triturating particles of rock, that there is good evidence that on each acre of land, which is sufficiently damp and not too sandy, gravelly or rocky for worms to inhabit, a weight of more than ten tons of earth annually passes through their bodies and is brought to the surface. ”

“ So that, if a small fraction of the layer of fine earth, 0.2 of an inch in thickness, which is annually brought to the surface by worms, is carried away, a great result cannot fail to be produced within a period which no geologist considers extremely long.
Archæologists ought to be grateful to worms, as they protect and preserve for an indefinitely long period every object, not liable to decay, which is dropped on the surface of the land, by burying it beneath their castings. ”

“ When worms make their burrows through earth abounding with little stones, no doubt many will be unavoidably swallowed; but it must not be supposed that this fact accounts for the frequency with which stones and sand are found in their gizzards. For beads of glass and fragments of brick and of hard tiles were scattered over the surface of the earth, in pots in which worms were kept and had already made their burrows; and very many of these beads and fragments were picked up and swallowed by the worms, for they were found in their castings, intestines, and gizzards. ”

“ Worms are known to have existed ever since late Proterozoic time, as proved by the occurrence of tracks, borings and more rarely delicate impressions on rock surfaces. Because of their softness they have rarely been well fossilized and are, therefore, of no great evolutionary or geological importance. ”

“ Thus we find the humours and substances of the body, upon putrifaction, to produce strange kinds of moving Vermine: the putrifaction of the slimes and juices of the Stomack and Guts, produce Worms almost like Earth-worms, the Wheals in childrens hands produce a little Worm, call'd a Wheal-worm: The bloud and milk, and other humours, produce other kinds of Worms, at least, if we may believe what is deliver'd to us by very famous Authors ”

“ On the number of worms which live within a given space.—We will now show, first, what a vast number of worms live unseen by us beneath our feet, and, secondly, the actual weight of the earth which they bring up to the surface within a given space and within a given time. Hensen, who has published so full and interesting an account of the habits of worms, calculates, from the number which he found in a measured space, that there must exist 133,000 living worms in a hectare of land, or 53,767 in an acre. ”

“ Whilst many of the subterraneous insects, as the common worms, seem to retreat so deep into the earth as not to be enlivened or awakened by the difference of our winter days; and stop up their holes with leaves or straws, to prevent the frosts from injuring them, or the centipes from devouring them. The habits of peace, or the stratagems of war, of these subterranean nations are covered from our view; but a friend of mine prevailed on a distressed worm to enter the hole of another worm on a bowling-green, and he presently returned much wounded about his head. ”

“ The body of a large worm consists of from 100 to 200 almost cylindrical rings or segments, each furnished with minute bristles. The muscular system is well developed. Worms can crawl backwards as well as forwards, and by the aid of their affixed tails can retreat with extraordinary rapidity into their burrows. ”

“ When a worm comes to the surface to eject earth, the tail protrudes, but when it collects leaves its head must protrude. Worms therefore must have the power of turning round in their closely-fitting burrows ”

“ And likewise the great common Earth-worms, for curing it. Neither is it without ground that this Worm [or Scarabæus] we mention, far exceed all the rest of them that are endued with Virtues, healing Diseases. The Cantharides come far short of it, and the sky coloured Flies, which are formed onely in Carkasses, are far short of the Cantharides. In the next place follow those greater Flies, that usually stay in men’s houses, and keep buzzing about till they can find some raw Flesh, whereon they cast their filth in the likeness of small Eggs or Knits, which become Worms in a days time. ”

“ A very intelligent lady, born in the woods of Northern New England, told me that, in her childhood, these worms were almost unknown in that region, though anxiously sought for by the anglers, but that they increased as the country was cleared, and at last became so numerous in some places, that the water of springs, and even of shallow wells, which had formerly been excellent, was rendered undrinkable by the quantity of dead worms that fell into them. ”

“ Every morning during certain seasons of the year, the thrushes and blackbirds on all the lawns throughout the country draw out of their holes an astonishing number of worms, and this they could not do, unless they lay close to the surface. ”

“ So again on a recently disinterred pavement of a Roman villa at Abinger (hereafter to be described) the worms pertinaciously opened their burrows almost every night, when these had been closed by being trampled on, although they were rarely able to find a few minute stones wherewith to protect them.
Intelligence shown by worms in their manner of plugging up their burrows.—If a man had to plug up a small cylindrical hole, with such objects as leaves, petioles or twigs, he would drag or push them in by their pointed ends ”

“ The fourth group, Vermes (Worms) , are animals with a bilateral or two-sided body, which is sometimes divided into segments, but without jointed appendages. Those which concern the student of fossils are the tube-making worms, the errant or wandering worms which form casts like the lob-worm, and the burrowing kinds whose crypts or dwellings become filled with solid material derived from the surrounding mud. ”

“ During the summer when the ground is dry, they penetrate to a considerable depth and cease to work, as they do during the winter when the ground is frozen. Worms are nocturnal in their habits, and at night may be seen crawling about in large numbers, but usually with their tails still inserted in their burrows. By the expansion of this part of their bodies, and with the help of the short, slightly reflexed bristles, with which their bodies are armed, they hold so fast that they can seldom be dragged out of the ground without being torn into pieces. ”

“ Often in the evening or early morning, or during rain, you will see worms near their houses. You may find them with their heads just put out of their doors. You will see the worm casts in early day or after rain. It is then the worms dare to come out. Sun and heat dry worms up very fast, and so kill them. ”

“ The Worms are to be gathered at such a time as the Earth first opens it self after the cold Season, and may be dig’d out, that so you may have the Worms before they creep forth out of the Earth, and have enervated each other by their coition, for when they are thus gotten they are endued with wonderfull virtues, and are far more efficacious than they113 be afterwards. ”

“ But M. D’Archiac must have thus argued from inner consciousness and not from observation, for worms abound to an extraordinary degree in kitchen gardens where the soil is continually worked, though in such loose soil they generally deposit their castings in any open cavities or within their old burrows instead of on the surface. Hensen estimates that there are about twice as many worms in gardens as in corn-fields. ”

“ For as soon as ever the Worms do perceive any thing given to the Sick, which is contrary to them, they presently hide themselves (or run to holes) and do wreath themselves into a kind of Ring, and pass out with the Excrements. But if they perceive any sweet thing which is pleasant to them to be given to the Sick, they do receive their nourishment thencefrom and remain alive. ”

“ And these are but a few of the evidences of the wonderful action of worms, collected by the activity of Charles Darwin and his sons.
Earthworms were not only scrutinised in their out-of-door work, but were kept in confinement and studied. It appears they swallow earth both to make their burrows and to extract all nutriment it may contain; they will eat almost anything they can get their skin over. From careful calculation it was shown that worms on an average pass ten tons of the soil on an acre of ground through their bodies every year. ”

“ On the other hand, whenever a large number of leaves are drawn into the burrows, the worms seem to subsist chiefly on them, for few earth-castings are then ejected on the surface. This difference in the behaviour of worms at different times, perhaps explains a statement by Claparède, namely, that triturated leaves and earth are always found in distinct parts of their intestines.
Worms sometimes abound in places where they can rarely or never obtain dead or living leaves; for instance, beneath the pavement in well-swept courtyards, into which leaves are only occasionally blown. ”

“ Notwithstanding these cases, if we consider the evidence above given, there can be little doubt that the fragments, which serve as millstones in the gizzards of worms, suffer, when of a not very hard texture, some amount of attrition; and that the smaller particles in the earth, which is habitually swallowed in such astonishingly large quantities by worms, are ground together and are thus levigated. ”

“ If worms are able to judge, either before drawing or after having drawn an object close to the mouths of their burrows, how best to drag it in, they must acquire some notion of its general shape. This they probably acquire by touching it in many places with the anterior extremity of their bodies, which serves as a tactile organ. It may be well to remember how perfect the sense of touch becomes in a man when born blind and deaf, as are worms. ”

“ When seen swimming in the water it presents the appearance of a long, many-ringed worm, which impels itself through and by the aid of its hundreds of flat, oar-like legs. Closer inspection reveals the startling fact that this seemingly single worm is really a multiple worm—six or more individuals being joined together, thus forming a living chain. This creature reproduces itself by fissigemation; that is, when the young worms arrive at a certain age they separate from the parent worm and begin life as individuals. ”

“ But all other Worms (like the four higher tribes of animals) possess a genuine body-cavity and a vascular system connected with it, which is filled with blood; hence we class them together as Cœlomati.
The main division of Bloodless Worms (Acœlomi) contains, according to our phylogenetic views, besides the still living Flat-worms, the unknown and extinct primary forms of the whole tribe of Worms, which we shall call the Primæval Worms (Archelminthes) . The type of these Primæval Worms, the ancient Prothelmis, may be directly derived from the Gastræa (p. 133) . ”

“ Large earthworms are nipped up with the jaws and laboriously poked in with the hands, the fingers being so placed as to clean the worm of adherent soil and other impurities. Very large worms are shaken, twisted, pressed against the ground and gulped down with convulsive movements, but not unfrequently the tip-end remains for some minutes sticking out of the tightly shut mouth. ”
