STRUCTURE OF BIRDS

Birds may be said to constitute an isolated class of beings. They are distinguished by certain characters from all other animals: their classification does not pass into any other, and cannot, therefore, be consistently introduced into the supposed chain or gradation of natural bodies.

The skeleton or bony frame of birds is in general lighter than in quadrupeds. They have the largest bones of all animals, in proportion to their weight; and their bones are more hollow than those of animals that do not fly: air-vessels also enable them to blow out the hollow parts of their bodies, when they wish to make their descent slower, rise more swiftly, or float in the air. The spine is immovable, but the neck has a greater number of bones, (never less than nine, and varying from that to twenty-four,) and consequently of joints, and more varied motion, than in quadrupeds. The breast-bone is very large, with a prominent keel down the middle, and is formed for the attachment of very strong muscles: the bones of the wings are analagous to those of the fore-legs in quadrupeds, but the termination is in three joints or fingers only, of which the exterior is very short. This will be better understood by the annexed:

The muscles that move the wings downwards, in many instances, are a sixth part of the weight of the whole body; whereas those of a man are not in proportion one hundredth part so large. The centre of gravity of their bodies is always below the insertion of their wings to prevent them falling on their backs, but near that point on which the body is, during flight, as it were, suspended. The positions assumed by the head and feet are frequently calculated to accomplish these ends, and give to the wings every assistance in continuing the progressive motion. The tail also is of great use, in regulating the rise and fall of birds and even their lateral movements. What are commonly called the legs are analogous to the hind legs in quadrupeds, and they terminate, in general, in four toes, three of which are usually directed forwards, and one backwards; but in some birds there are only two toes, in others three.

Birds exceed quadrupeds in the quantity of their respiration, for they have not only a double circulation, and an aerial respiration, but they respire also through other cavities beside the lungs, the air penetrating through the whole body, and bathing the branches of the aorta, or great artery of the body, as well as those of the pulmonary artery.

Birds are usually classed according to the forms of their bills and feet, from those parts being connected with their mode of life, food, &c. and influencing their total habit very materially.

THE RHINOCEROS BIRD

This curious bird is of the order Picæ, or Pies, and of the genus Buceros, consisting of birds of rather large size, and distinguished by the disproportionate forms of their beaks, which are often still further remarkable for some kind of large prominence on the upper mandible. The most conspicuous species is the Buceros Rhinoceros of Linnæus, commonly called the Rhinoceros Bird.

The Rhinoceros Bird.

Its general size is that of a Turkey, but with a much more slenderly proportioned body. Its colour is black, with the tail white, crossed by a black bar: the beak is of enormous size, of a lengthened, slightly curved, and pointed shape, and on the upper mandible, towards the base, is an extremely large process, equal in thickness to the bill itself, and turning upwards and backwards in the form of a thick, sharp-pointed horn, somewhat resembling the horn of the rhinoceros. The use of this strange proboscis is by some supposed to be that of enabling the bird more easily to tear out the entrails of its prey; but others affirm that it is not of a predaceous nature, feeding only on vegetable substances. This bird is principally found in the East Indian Islands. A remarkably fine specimen was preserved in the Leverian Museum.

THE SKETCH-BOOK

RECOLLECTIONS OF A WANDERER

A scene on the coast of Cornwall

A short time before my departure from the hamlet of Landwithiel,⁴ I was awoke early one morning by the roaring of the wind in the huge old chimney of my room—the whole tenement, indeed, occasionally shook as a violent gust swept down the valley, tossing the branches of the stout old tree before the door to and fro in a way that threatened at last to level them with the dust. The very briny scent of the atmosphere convinced me there was some sea running in the bay; and it was the more unexpected as we had had no tokens of a storm for several days previous. From the peninsular situation of this county, surrounded on almost every side with the restless ocean and exposed to the wide sweep of the Atlantic, it may be supposed that storms are of frequent occurrence. As on the present occasion, they often come with little or no warning; and the effects of a hurricane in the distant main, far outstripping the wind, sometimes rolls with tremendous fury towards our western shores, on which the sea is encroaching in every part.

Landwithiel was a wild little place. It was essentially a "fishing village." The people ploughed the deep, not the land; and the constant exposure—blow high, blow low—on the restless sea, endued its inhabitants, and the Cornish fishermen generally, with a fearlessness of danger and boldness of character almost unequalled in these islands. The lives and pursuits of the two great classes in this county—the maritime and mining population—are widely opposite to each other. The one class pass their existence on the stormy waters of the deep, whilst the other labour far below the surface of the earth; each being continually exposed to numberless perils and dangers.

When I descended below I found my host already astir; so after attending well to the inward man, I lost no time in starting towards the harbour. As I formerly described, this comes abruptly in sight round a sharp angle, at some elevation from the beach. On the upper part of the descent the road was flanked on each side with a row of cottages, the street being so steep that steps were formed in many parts to aid the progress of the passenger. This gave an air of singularity and wildness to the place, which was aided by the boldness of the surrounding scenery. The street bore all the marks of the occupation of the inhabitants—nets hanging to dry—strings of fish—an old oar—or a "fisher's wife" broiling fish for her husband's breakfast—met the eye on either side.

On clearing the street, I observed a larger throng on the old pier than was wont to gather there on ordinary occasions. There was obviously some unusual subject of interest agitated amongst them; so I turned from my course and joined the group.

A gale is an important event in a fishing town. Independent of the interest naturally felt for the various craft belonging to the place which may happen to be afloat, there may be wrecks or other marine casualties to excite the interest or cupidity of the observer.

There was a tremendous tumbling sea rolling into the little bay, when I drew towards the pier. At the further end was a group of persons in earnest conversation, whom I distinguished as the knowing ones and long-heads of the place; while their younger companions were engaged in parties walking briskly to and fro on the pier. A tier of boats had been carefully drawn up high and dry beyond the wreck left by the last spring tide. Four or five, however, were afloat, and lurching heavily alongside the pier, whither the tide had not long reached; the wind rattling amongst the masts, shrouds, and half-bent sails of some craft which had just run in for shelter from the impending storm. My recent adventure had made me pretty well acquainted with most of the persons around: and I learned that a ground swell had been observed along shore the preceding night. This phenomenon is generally occasioned by a storm in the Atlantic, with a westerly wind; and it affords to the old fishermen an almost certain indication of approaching foul weather.

"A stiff bit of a gale, this same, Master Charles," said an old tar, giving an energetic jerk to his trousers, "Ay, ay, old boy," he replied, "this wind is not blowing for nothing, you may take my word for it; but if the Jane and the Susan hove in sight I'd not mind a bit for all that; we've not a stick afloat but her."

"What! is Sam Clovelly⁵ out this morning, Helston?" I anxiously inquired of the pilot, who was a manly, excellent sort of fellow. He had grown grey with service, and there was something in the steady eye and calm decision of his look that marked him out as no common character.

"Yes, sir, we have no tidings of him yet, and the sky looking as black, yonder, as the face of a negro; but we'll hope that he's run out of harm's way before now."

As the morning waxed apace, the interest in the fate of the Jane and Susan became more evident amongst the by-standers. Every stick that came in sight cut out conversation; but many an eye was cast anxiously to windward in vain for poor Sam Clovelly and his brother Arthur, who had been out since the preceding night. Presently the two little orphan sisters of the missing men came upon the pier, and Helstone, the pilot, and some of the others anxiously endeavoured to cheer and console them.

"I'll be bound they've run for – port long ago, darlings, so don't cry now, Jane; the old craft's stood many a stronger breeze than this; now, wipe your eyes, there. Poor things," he said, turning to me, as the children went farther on the pier, "their two brothers are the only friends they have got in the world, and if they are gone who is to take care of them? Their father, old Sam Clovelly, was lost—I recollect the time well—somewhere off Milford; leaving his wife, with two stiff tidy bits of lads, and likely to increase the family; well, sir, she took to her bed, with the shock, and never rose from it more, after giving birth to these two little girls, leaving poor Sam and Arthur to struggle on like a cutter in a heavy sea. But God Almighty never deserts the innocent, sir—you've seen that, I dare say? Sam's been a steady lad, and has prospered, and he and Arthur have never forgotten their mother's dying words, and have been very kind to their sisters; but, come what will, the orphans shall never want a friend as long as Charley Helston has a home or a bit of bread to offer them."

We now again reverted to the state of the day. As the gale swept on, numberless craft were running along the coast towards – port, for shelter. A crack Fowey-man now making a board till she "eat out" of the wind a North-countryman right ahead—now with her helm-a-lea, and now careering along with a heavy following sea on either quarter—kept our attention on the alert. Presently a steamer came in sight bearing up across the bay towards – Head. The white rush of steam from her safety-valves was well made out by the blackness of the windward horizon; and contrasted with the dense puffs of smoke from her funnel, which were instantly dispersed or carried in heavy patches to leeward. The glory of modern discoveries is unpopular with our coasting-seamen, and the mate of a coaster, who was watching her movements, observed that "we should not have a lad fit to hand a sail or man a yard soon with their cursed machinery."

As she passed on her course "cleaving blast and breaker right ahead," with her weather-wheel often spinning in the air, and as the sky darkened and the waves roared louder, I thought with deep interest on what might even now be the fate of those, without whose friendly aid I should have been lying on a rocky pillow and seaweed for my shroud, near Dawlish's Hole. The weather now became entitled to the formidable name of a storm, but some time had yet to elapse before darkness added its horrors to the scene of desolation.

Heavy masses of breakers were continually striking the pier-head with fearful crashes; now bursting over, amid seas of spray, with resistless impetuosity, drenching every one under its lee; now recoiling for a brief moment, as if to gather strength, leaving a smooth, hollow waste of oily sea—like the treacherous pauses of human passion,—and then returning with wilder haste and tenfold added fury to the onset.

The morning was waning away. I left the pier, and bent my course away from Landwithiel.

The path I pursued led along the summit of the cliffs; oftentimes winding so close round the edge of a projecting acclivity, that it required a clear head and a steady foot, for one false step would have been instant destruction. The coast below me was justly entitled to take its place amongst the finest rock-scenery in the island; and exhibited in its grandest form, the peculiarly wild and picturesque nature of the coast of Cornwall. After working my way against a head-wind for three or four miles, I took shelter in Dawlish's Watch Tower, an old half-ruined building, which commanded an almost boundless look-out. Nearly right opposite to this station lay the Wolf-stone, an insular, and almost inaccessible rock, which rose in deep water about three-quarters of a mile from land. Whilst scanning with my glass the windward horizon, I accidentally rested on this islet, and I had not looked long before my gaze was rivetted to it. Two individuals I fancied were standing near a pole which was erected on the highest point. These lone and unusual tenants of the sea-birds' home were obviously, from their motions, much agitated. A heavy driving shower, for a few minutes, wrapped it in mist. When this cleared off, the black and dreary front of the Wolf-stone became dimly visible through the tumultuous assemblage of gigantic breakers, that were every instant grappling with the steep which defied them. Another minute's observation and I was running at my utmost speed back to Landwithiel. The captives could be no other than Sam and Arthur Clovelly.
