back a little, and sat down upon an eminence; the snake in a few moments slunk again to the earth, with a calm, placid appearance; and the birds soon after returned, and lighted upon the ground near the snake, first stretching their wings upon the ground, and spreading their tails, they commenced fluttering round the snake, drawing nearer at almost every step, until they stepped near or across the snake, which would often move a little, or throw himself into a different posture, apparently to seize his prey; which movements, I noticed, seemed to frighten the birds, and they would veer off a few feet, but return again as soon as the snake was motionless. All that was wanting for the snake to secure the victims seemed to be, that the birds should pass near his head, which they would probably have soon done, but at this moment a wagon drove up and stopped. This frightened the snake, and it crawled across the fence into the grass: notwithstanding, the birds flew over the fence into the grass also, and appeared to be bewitched, to flutter around their charmer, and it was not until an attempt was made to kill the snake that the birds would avail themselves of their wings, and fly into a forest one hundred rods distant. The movements of the birds while around the snake seemed to be voluntary, and without the least constraint; nor did they utter any distressing cries, or appear enraged, as I have often seen them when squirrels, hawks, and mischievous boys attempted to rob their nests, or catch their young ones; but they seemed to be drawn by some allurement or enticement, and not by any constraining or provoking power; indeed, I thoroughly searched all the fences and trees in the vicinity, to find some nest or young birds, but could find none. What this fascinating power is, whether it be the look or effluvium, or the singing by the vibration of the tail of the snake, or anything else, I will not attempt to determine—possibly this power may be owing to different causes in different kinds of snakes. But so far as the black snake is concerned, it seems to be nothing more than an enticement or allurement with which the snake is endowed to procure his fowl.—Professor Silliman's Journal.

Boring Marine Animals.

The most destructive of these is the Teredo Navalis, a fine specimen of which was exhibited at a recent meeting of the Portsmouth Philosophical Society. This animal has been said to extend the whole length of the boring tube; but this assertion is erroneous, since the tubes are formed by a secretion from the body of the animal, and are often many feet in length, and circuitous in their course. This was shown to be the fact, by a large piece of wood pierced in all directions. The manner in which it affects its passage, and the interior of the tubes, were also described. The assertion that the Teredo does not attack teak timber was disproved; and its destructive ravages on the bottom of ships exemplified, by a relation of the providential escape of his majesty's ship Sceptre, which having lost some copper from off her bows, the timbers were pierced through to such an extent as to render her incapable of pursuing her voyage without repair.

Anthracite, or Stone Coal.

Professor Silliman's last journal contains a very important article, illustrative of the practical application of this mineral; and the vast quantities of it that may be found in Great Britain renders the information highly valuable to our manufacturing interests. In no part of the world is anthracite, so valuable in the arts and for economical purposes, found so abundantly as in Pennsylvania. For the manufacture of iron this fuel is peculiarly advantageous, as it embraces little sulphur or other injurious ingredients; produces an intense steady heat; and, for most operations, it is equal, if not superior to coke. Bar iron, anchors, chains, steamboat machinery, and wrought-iron of every description, has more tenacity and malleability, with less waste of metal, when fabricated by anthracite, than by the aid of bituminous coal or charcoal, with a diminution of fifty per cent. in the expense of labour and fuel. For breweries, distilleries, and the raising of steam, anthracite coal is decidedly preferable to other fuel, the heat being more steady and manageable, and the boilers less corroded by sulphureous acid, while no bad effects are produced by smoke and bitumen. The anthracite of Pennsylvania is located between the Blue Bridge and Susquehannah; and has not hitherto been found in other parts of the state, except in the valley of Wyoming.

Holly Hedges.

At Tynningham, the residence of the Earl of Harrington, are holly hedges extending 2,952 yards, in some cases 13 feet broad and 25 feet high. The age of these hedges is something more than a century. At the same place are individual trees of a size quite unknown in these southern districts. One tree measures 5 feet 3 in. in circumference at 3 feet from the ground; the stem is clear of branches to the height of 14 feet, and the total height of the tree is 54 feet. At Colinton House, the seat of Sir David Forbes; Hopetown House, and Gordon Castle are also several large groups of hollies, apparently planted by the hand of Nature.—Trans. Horticultural Society.

Egg Plants.

In this country, the egg plant, brinjal, or aubergine, is chiefly cultivated as a curiosity; but in warmer climates, where its growth is attended with less trouble, it is a favourite article of the kitchen garden. In the form of fritters, or farces, or in soups, it is frequently brought to table in all the southern parts of Europe, and forms a pleasant variety of esculent.—Ibid.

Vinegar made from Black Ants.

It is singular enough, that a discovery of modern chemistry should long have been practically employed in some parts of Norway, for the purpose of making vinegar from a large species of black ant. The method employed in Norlanden is simply this: they first collect a sufficient quantity of these little animals, by plunging a bottle partly filled with water up to the neck in one of the large ant-hills; into which they naturally creep, and are drowned. The contents are then boiled together, and the acid thus produced is made use of by the inhabitants as vinegar, being strong and good.

Soil for Fruit Trees.

Low grounds that form the banks of rivers are, of all others, the best adapted for the growth of fruit trees; the alluvial soil of which they are composed, being an intermixture of the richest and most soluble parts of the neighbouring lands, with a portion of animal and vegetable matter, affording an inexhaustible store of nourishment—Trans. Horticultural Society.

Watch Alarum.

A patent has recently been procured for a most useful appendage to a watch, for giving alarm at any hour during the night. Instead of encumbering a watch designed to be worn in the pocket with the striking apparatus, (by which it would be increased to double the ordinary thickness), this ingenious invention has the alarum or striking part detached, and forming a bed on which the watch is to be laid; a communication being made by a lever, projecting through the watch case, to connect the works. This appendage is described to be applicable to any watch of the usual construction, and is by no means expensive.

THE MONTHS.

NOVEMBER.

November is associated with gloom, inasmuch as its days and nights
