An Inaugural Essay on the Vegetation of Plants-by
Samuel Stuart Griffin, Å. B. of Virginia.
Phoebe fave! Novus ingreditur tua Templa Sacerdos.
TIBULLUS.

The vegetable and mineral kingdoms present not this intimate connexion. There we are compelled to acknowledge an internal force, a vis vita, which performs every thing, governs all the processes, and subjects to its designs those agents which have an absolute empire over the mineral kingdom. Here every thing bows to the immutable laws of the affinities. No internal principle regulates the operation of natural agents, and hence we are empowered to determine, modify, and at pleasure vary the action of these different agents.

Plants, like animals, experience three different periods in the course of their existence: they have an origin, an increase, and a termination of life. All are found to spring from seeds. In examining a seed we find it to be composed of three principal parts: the corculum, the cotyledons, and integuments When we look abroad and behold the diversified enveloping the two former. The corculum, which appearances which nature every where presents to contains the embryo of the young plant, consists of our view, the mind pauses to inquire whence these a plumula and rostellum.

Hence, in the cabinets of the curious, seeds never
vegetate; but, when irrigated with water, they will
sprout in a very short time. This moisture, how-
ever, has its limits; too much is equally as noxious,
by rotting and destroying the seed, as its total ab-
sence proves a bar to vegetation.

Moisture alone will not effect the germination of plants. The concurrence of heat to a certain de Among inquiries of this kind, surely botanical re-gree is absolutely necessary. Seeds, we know, will searches claim a distinguished rank. The tender green and delicate texture of the leaf; the variegated painting of the flower; the lowly plant rising from the earth, gradually erecting and expanding itself into the stately tree, are objects which powerfully solicit our attention and regard.

not vegetate in water cooled to the freezing point.
During the chill blasts of winter, they remain in a
state torpid and benumbed; but when the spring,
with its genial warmth returns, the embryo starts
from its slumber into animated life.

Atmospheric air, or some other gas possessing I advance to the theme of vegetation, not with the properties of this air, is essentially necessary to the presumptuous hope that efforts so feeble and germination. Experiments attest that seeds will imperfect as these, can shed even a ray of new light not grow in the vacuum of an air-pump. From or discernment. The observations of others are this necessity of atmospheric air to germination, here assembled, and their experiments followed. I we readily explain the reason why seeds, lodged appear, then, merely in the hues of reflected vision. deep in the ground, will not vegetate; and why Let, therefore, the appeal which is now made to those nearest to the surface of the earth will be your generosity, shield me from severity! Regard found to spring first. me as enrolled in the lists of emulation, and not as offering at the shrine of vanity or arrogance.

When we draw a parallel between the vegetable and animal worlds, we are struck with the simili tude. Numerous and beautiful are the analogies which an inquiry of this nature unfolds. Compared in their state most perfect, the line of demarcation is sufficiently bold; but when we attend more mi nutely to the character of animals, we shall perceive that nature glides by degrees insensible from No. 15.-VOL. 9.

From experiments, it appears that seeds vegetate very quickly in oxygen gas, and still more so in oxymuriatic acid. According to the botanical lec tures of a learned Professor, whose pupil, with no small degree of exultation, I call myself, so truly astonishing are the effects of the oxymuriatic acid, that seeds, which had always refused to vegetate, were made to vegetate by irrigating the earth in which they were planted, with water having an impregnation of this acid.

According to Dr. Rutherford,* carbon and sulphur are attended with the same effect. Why sulphur and carbon should act in this manner, remains yet to be explored; as they have hitherto resisted chemical decomposition.

That earth is not absolutely necessary to the germination of seeds, can be easily demonstrated.— The seeds of different parasitic plants vegetate very quickly in the bark of other vegetables. Some seeds are found to quicken upon the most barren rocks; others germinate in the water and continue to grow entirely remote from the contact of earth. Of these last the lemna and faci afford an example.

Philosophers, it appears, have been much divided as to the effect of electricity upon germination. Ingenhour affirms, that the electric fluid is injurious; and even Sennebier, in his Vegetable Physiology, has upon this subject dropped a doubt: "Je ne dirai rien de l'electricité, puisque son influence est, au moins, douteuse." Dr. Darwin strenuously contends for the influence of both positive and negative electricity in accelerating the germination of plants. The Abbe Bertholon, who has written a volume solely upon the effect of electricity as to vegetables, is of opinion, from numerous experiments, that the germination of the seed and future growth of the plant are increased by electricity, both natural and artificial. The renowned discoverer of the azotic gast is fully persuaded of its utility. Amid the contrariety of sentiments I dare not decide.

"Non nostrum inter." Ios "tantas componere lites."

Light, that subtile fluid, whose influence is so generally diffused, from which the trees derive their tender green, and from whose touch the very dead‡ creation, as it were, assumes a mimic life, is found injurious to the germination of seeds. Ingenhour and Sennebier have clearly established, that seeds always germinate faster when excluded from light, than when exposed to its influence. Indeed the penetration of the gardener has for a long time discovered the necessity of covering seeds, intended for germination, with a stratum of earth.

Among other causes inimical to germination, may be enumerated the noxious exhalations of many plants. Some there are which do not permit others to grow near them, and which seem to prefer a solitary life. This circumstance has given rise to a division of plants into solitarice and sociatæ. plants are found so remarkably destructive to vegetable growth, as to present before them a dreary waste without a vestige of vegetation. The Bohon

This beautiful idea is borrowed from the poet of nature. He sings

"The very dead Creation, from thy touch,
Assumes a mimic life. By thee resin'd
In brighter mazes the relucent stream
Plays on the mead. The precipice abrupt
Projecting horror on the blacken'd flood,
Softens at thy return. The desert joys,
Wildly, through all his melancholy bounds,
Rude ruins glitter; and the briny deep,

Restless, reflects a floating gleam

Upas, whose deleterious effects the poetic genius o Darwin has so beautifully described, here stands in relief.

"No spicy nutmeg scents the vernal gales,

Nor towering plantain shades the mid-day vales,
No grassy mantle hides the sable hills,
No flowery chaplet crowns the trickling rills,
Nor tufted moss, nor leathery lichen creeps,
In russet tapestry o'er the crumbling steeps.

He also observed that the motion of the sap was more rapid through young than old branches, and that it flowed more copiously from an inverted, than from an erect branch.

It is stated that the consumption of raw cotton in France and Switzerland in 1825, was 230,000 bales; in 1826. 280,000 bales. The present consumption in the United States is supposed to be from 175 to 200,000 bales; and if our domestic manufactures continue to increase, as they have done for a few Mr John Fitch, of Mansfield, Conn. who has years past, our consumption at home will soon ex-kindly devoted much time to me on the subject, esceed France and Switzerland united.

As respects the care of the cocoon, Dondola considers the labour of 12 persons sufficient to gather from the bushes and put out to dry, 6000 pounds of balls per day. Mr. Fitch declares, that 5 persons in 15 days can pick off and reel 40 pounds of silk, or 130,000 cocoons.

I will now give, with some detail, a description of the food best adapted to the purpose of producing

the largest quantity of the first quality of silk, and| of the most approved mode of raising it. As I before mentioned, the White Mulberry appears to suit the animal better than any other, though in Calabria the Red is preferred, and in Grenada the Black alone is cultivated. If a worm is supplied with a mixture of the different kinds, it will first eat the White, then the Red, and lastly the Black.

He thinks. they should be kept flat like espaliers, and not allowed to shoot forward towards the other rows. Six feet in height he proposes as the maximum, and the leaves must not be taken before the fourth year. (To be concluded in our next.)

The food next best adapted to the animal is the Lettuce, and when the mulberry cannot be procured it should be used. Experiments within a few years seem to indicate that the cabbaged Lettuce, if the animals and leaves be preserved quite warm, will answer, not only for an occasional meal, but for their only nourishment. If these experiments are verified, a far more abundant supply can be raised more easily, and one great advantage is gained of always having dry food at command, by means of the internal leaves; during the longest season of rain. Many other articles have been employed at different times, but they all have failed of producing good silk. Considering the mulberry then, as the suitable food, I will now give a description of the best modes of culture, so many plans having been proposed that too much time would be occupied in a complete ac

count.

This tree is termed, in Botanical language, Morus, and of this there are several species, as the Alba, Rubra, Nigra, &c. As we have decided the White to be the most useful, I shall confine my attention to it, though there is no doubt the same plans will answer for all.

The middle bears a foliage of a dark green colour, very thick, and produces abundance of leaves, is very nutritious, and the worms fed on it grow very fast; but it does not produce much silk. The double leaved is by far the best; though not so juicy, it abounds in the resinous matter that becomes the silk. In this kind, the leaves are small, of a dark, shining green, and divided into two or three lobes.

TO REMOVE FROM MILK THE TASTE OF GARLIC. MR. SKINNER, Harford county, June 14, 1827.
