Alcheringa

“ The Sea-pens form a very distinct order of the Alcyonaria. They are the only Alcyonarians that are not strictly sedentary in habit, that are capable of independent movement as a whole, and exhibit a bilateral symmetry of the colony. No genera have yet been discovered that can be regarded as connecting links between the Pennatulacea and the other orders of the Alcyonaria. ”

“ But so beautiful is Alcina, that none can withstand her if once she looks on them, therefore fly while you may and ask counsel of Logistilla if there is aught that you would know.’
‘Oh, tell me, good tree, how I can escape without crossing the path of the cruel Alcina?’ cried Roger.
‘There is a way,’ answered the tree, ‘but it is rough to the feet, and beset by fierce and ill-tongued men, placed there by the fairy. He who would quit Alcina’s isle needs open eyes and deaf ears.’
‘I will have both,’ said Roger.
But, alas! he boasted overmuch, as young men are wont to do. ”

“ The inflorescence is a long upright raceme. These bristles are arranged in whorls of 5 and 10, of which the uppermost alternate with the sepals.—Alchemilla (Ladies-mantle; Fig. 501) has 8 green perianth-leaves in two whorls (some authorities consider the four outer as an epicalyx, and the flower therefore apetalous) , and 4 stamens alternating with the innermost whorl. There is only one carpel with a basal style and capitate stigma. The flowers are small and greenish, the filaments jointed. The anthers open by one extrorse cleft. The leaf-sheath entirely envelops the stem ”

“ The spicules constitute one of the most characteristic features of the Alcyonaria. They are not found in Cornularia, Stereosoma, in a recently discovered genus of Gorgoniidae (Malacogorgia) , in certain Pennatulacea and in Heliopora; and it is probable that they may be absent in some local varieties of certain species of Clavularia.
The spicules of Alcyonaria consist of an organic matrix {335}supporting a quantity of crystalline calcium carbonate. In some cases (Xenia) the amount of inorganic salt is so small that the spicule retains its shape after prolonged immersion in an acid ”

“ The castings, indeed, of a single pair of king-fishers would of itself suffice to account for all the fish bones one meets with by the banks of ponds and streams, for the beautiful Alcedo is a voracious fish-devourer, and his hole going backwards and upwards some three or four feet into the bank, invariably a perfect charnel-house of bleached fish bones of minnows and troutlets. ”

“ The Anhinga in truth is the very first of all fresh-water divers. With the quickness of thought it disappears beneath the surface, and that so as scarcely to leave a ripple on the spot; and when your anxious eyes seek around for the bird, you are astonished to find it many hundred yards distant, the head perhaps merely above water for a moment; or you may chance to perceive the bill alone gently cutting the water, and producing a line of wake not observable beyond the distance of thirty yards from where you are standing. With habits like these it easily eludes all your efforts to procure it. ”

“ In about an hour from Coin, we reached a clear stream, which, confined in a deep gulley, singularly scooped out of the solid rock, winds round at the back of Alhaurin, and tumbles over a precipice on the side of the impending mountain. The crystal clearness of the water and beauty of the spot, tempted us to halt and spread the contents of our alforjas on the green bank of the rivulet, though the white houses of Alhaurin, situated immediately above, peeped out from amidst trelissed vines and perfumed orange groves, seeming to beckon us on. ”

“ Look at the slim slip of a boy who gravely walks at the head of this team of enormous fawn-coloured oxen, toilsomely dragging their ponderous load up a hill so steep as almost to need a ladder to ascend. The urchin cannot be more than ten or eleven, and in any other country would alternately skip and idle, or at least allow his attention to wander with every fresh object that struck his fancy. ”

“ The “branching alcyonite,” on the other hand, did, I imagine, grow, like a Coral or “Encrinite,” in one place; and I suppose it was much like an ice-plant in form, but that it had the power of drawing back at will all its branches and suckers—which were, in fact, the creature’s arms and tentacles—into the root or bulb which formed its base. The “sponges,” a large family, we know are not extinct; and the conformation of the living individuals fully bears out all the marvels which have been predicated of the fossil animal. I have handled these creatures, fresh from the sea, at Brighton ”

“ In regions where red clover is declining on account of lack of lime, one may see some alsike. The rule is to mix alsike with the red at the rate of one or two bushels of the former to six bushels of the latter. As the seed of the alsike is hardly half as large as that of the red, the proportion in the mixture is greater than some farmers realize. The practice is an excellent one where the red will not grow, and the alsike adds fertility, but when the soil has been made alkaline, the red clover should have nearly all the room. Alsike is a heavy producer of seed. ”

“ Consequently, the medium red variety, the mammoth, the crimson, the Japan and the burr varieties stand high in such adaptation. The alsike, living longer, is lower in its adaptation, and alfalfa, because of its long life, stands lowest in this respect. The small, white variety is almost invariably grown or found growing spontaneously along with grasses, hence no definite place has been or can be assigned to it in the rotation. ”

“ The name "alfilerilla" is Spanish, coming from alfiler, a needle, and refers to the long, slender beak of the carpels. By corruption it has become "filaree."
This plant is found in abundance everywhere, and is one of our most valuable forage-plants. It varies greatly in size, and becomes very rank in growth where the soil is rich. Ordinarily, it makes its appearance soon after the beginning of the rainy season, as a rosette of leaves lying upon the ground, and later it sends up its reddish stems. ”

“ The flesh of the Anhinga, after the bird is grown, is dark, firm, oily, and unfit for food, with the exception of the smaller pectoral muscles of the female, which are white and delicate. The crimpings of the two middle tail-feathers become more deeply marked during the breeding season, especially in the male. When young, the female shews them only in a slight degree, and never has them so decided as the male. ”

“ The action is indeed performed by the Anhinga at all periods of its life. At an early age the young utter a low wheezing call, and at times some cries resembling those of the young of the smaller species of Herons. From birth they are fed by regurgitation, which one might suppose an irksome task to the parent birds, as during the act they open their wings and raise their tails. I have not been able to ascertain the period of incubation, but am sure that the male and the female sit alternately, the latter however remaining much longer on the nest. ”

“ In Alcyonium and other Alcyonaria gland cells also occur in the stomodaeum, and it is probable that they secrete a fluid capable of digesting to some extent the food as it passes through. The most important part of the digestion, however, is performed by the six "ventral" mesenteric filaments.
Attention has already been drawn to the fact (p. 330) that two regions of the zooids of the colonial Alcyonaria can be recognised. ”

“ How poor and bungling are all the imitations of art! When I have the pleasure of seeing you next, we shall sit down—nay, kneel down—and admire these things."—Hogarth to Ellis.
The Alcyonaria are so designated from their principal type, that of the Alcyons. The fresh-water species are composed of a fleshy, sponge-like mass, consisting of vertical, aggregated, membranaceous tubes, which are open on the surface. In these tubes the polyps, which are Isidians, are located. ”

“ The sea urchin lays eggs, and from these eggs come the young urchins. (What other animal have we already found, that lays eggs?) When they are babies they don't look a bit like their parents. And here is another thing that the sea urchin does that you will remember when we come to kangaroos. Some of the sea urchins carry their babies in pouches. They fold their spines over their babies just as you carry a doll in your arms. ”

“ Many species are prettily marked by nature, others are rendered handsome by polishing. O. subulata is small, and pointed like a mitre. The common olive is white, with brown, waved lines. O. irrisans is ornamented with yellow zigzag lines: it has two brown zones. O. oriza, the little rice-olive, is white.
"I should have noticed the small genus Ancilla, formerly Ancillaria, which is very near both to Terebellum and Oliva. The columella has a varix at the base, which distinguishes it from Terebellum, and it wants the canal which separates the volutions of Oliva.
"There are several fossil species. ”

“ The minute cells in which the polyps are lodged are not always arranged in the same manner. Sometimes the cells occupy one side only; in other instances they occupy both; sometimes they are grouped like the pipes of an organ, at others they are ranged spirally round the stem, or arranged at intervals, forming horizontal rings round it.
The Alcyonaria are very common on some parts of our coast, where scarcely a stone or shell is dredged up that does not support one or more specimens known to the fishermen as "cow's paps," "dead men's fingers," and other popular names. ”

“ Such a regular urchin as has here been described lives with the mouth downwards, preferring a hard floor, on which it creeps by its podia and its radioles, constantly scraping the algae and seaweeds from the rock with its teeth and so feeding itself. If it does not bore a hole, or is not protected by long needle like radioles, it may grasp bits of sea-weed or other objects with its pedicellariae and hide beneath them from the fish that seek it for food.
The Irregular urchins (fig. 3) have been modified for another way of life. Some of them live in mud or ooze, through which they creep. ”

“ Between the rows of knobs are five double rows of holes, like pin-pricks. Out of these grow such little suckers as I told you the star-fish had.
In some countries the sea-urchins are small—not much larger than a dime. In warmer seas the urchins grow large, even as large as a large orange. People often use these larger ones for food.
The sea-urchin walks on his spines, as the cross-star-fish does on his. But as the quills of the urchin are all around him, like a ball-cover, his walk is a roll! By the little suckers he can cling to the rocks, and he can climb up their sides. ”

“ The flight of the Anhinga is swift, and at times well sustained; but like the Cormorants, it has the habit of spreading its wings and tail before it leaves its perch or the surface of the water, thus frequently affording the sportsman a good opportunity of shooting it. When once on wing, they can rise to a vast height, in beautiful gyrations, varied during the love-season by zigzag lines chiefly performed by the male, as he plays around his beloved. At times they quite disappear from the gaze, lost as it were, in the upper regions of the air ”

“ In some cases the spicules are smooth double clubs, rods, discs, or irregular granules, and in Sarcophyllum, Chunella, some species of Umbellula and others, there is no calcareous skeleton. The tuberculated spindles, so common in other Alcyonaria, are not found in any species. In most genera a horny, or calcified horny rod is embedded in the central part of the axial polyp, serving as a backbone or support for its muscles. ”

“ Their plumage is dense and close, and commonly of blue or green hues. They are scattered over the world, but Australia with the adjacent isles, and South America, contain the greatest number of species.
Genus Alcedo. (Linn.)
The beak in this genus is very straight, sharp, compressed through its whole length, with the gape ample; the upper mandible is not at all bent at the point. The wings are somewhat rounded, the third quill being the longest. The tail is very short, scarcely reaching beyond its coverts. The feet are very weak; the outer and middle toes united ”

“ This colony has for its principal foundation a living Alcyonium, which covers the carapace, and as it develops, adapts itself perfectly to all the inequalities of the cephalothorax; one might consider it an integral part of the crab. Sertulariæ, Corynes, Algæ, develop themselves on this Alcyonium, and the Dromia, masked by this living rock which it carries on its shoulders like the fabled Atlas, marches gravely in pursuit of her prey. She has no fear of arousing the attention of her enemies. The greatest vigilance cannot prevent the sudden attack of these dangerous neighbours. ”

“ When alive, it is a dangerous and formidable enemy in its native element, as it is not blessed with a very amiable temper. And when stuffed, it is an object of great curiosity, and well worthy of a place in a museum. The echinus, or sea-urchin, is another species of the class and order vermes, mollusca. It does not attain the size of the orbus major, being seldom found more than five inches in length, but it is covered with sharp prickles, and can equally inflate itself when angry. The flesh is eaten with oil, vinegar, and pepper; and in flavour resembles the lobster. ”
