Genesis 3:18

Thorns also and thistles, etc. - Instead of producing nourishing grain and useful vegetables, noxious weeds shall be peculiarly prolific, injure the ground, choke the good seed, and mock the hopes of the husbandman; and thou shalt eat the herb of the field - thou shalt no longer have the privilege of this garden of delights, but must go to the common champaign country, and feed on such herbs as thou canst find, till by labor and industry thou hast raised others more suitable to thee and more comfortable.

In the curse pronounced on the ground there is much more implied than generally appears. The amazing fertility of some of the most common thistles and thorns renders them the most proper instruments for the fulfillment of this sentence against man. Thistles multiply enormously; a species called the Carolina sylvestris bears ordinarily from 20 to 40 heads, each containing from 100 to 150 seeds.

Another species, called the Acanthum vulgare, produces above 100 heads, each containing from 3 to 400 seeds. Suppose we say that these thistles produce at a medium only 80 beads, and that each contains only 300 seeds; the first crop from these would amount to 24,000. Let these be sown, and their crop will amount to 576 millions. Sow these, and their produce will be 13,824,000,000,000, or thirteen billions, eight hundred and twenty-four thousand millions; and a single crop from these, which is only the third year's growth, would amount to 331,776,000,000,000,000, or three hundred and thirty-one thousand seven hundred and seventy-six billions; and the fourth year's growth will amount to 7,962,624,000,000,000,000,000, or seven thousand nine hundred and sixty-two trillions, six hundred and twenty-four thousand billions. A progeny more than sufficient to stock not only the surface of the whole world, but of all the planets of the solar system, so that no other plant or vegetable could possibly grow, allowing but the space of one square foot for each plant.

The Carduus vulgatissimus viarum, or common hedge thistle, besides the almost infinite swarms of winged seeds it sends forth, spreads its roots around many yards, and throws up suckers everywhere, which not only produce seeds in their turn, but extend their roots, propagate like the parent plant, and stifle and destroy all vegetation but their own.

As to Thorns, the bramble, which occurs so commonly, and is so mischievous, is a sufficient proof how well the means are calculated to secure the end. The genista, or spinosa vulgaris, called by some furze, by others whins, is allowed to be one of the most mischievous shrubs on the face of the earth. Scarcely any thing can grow near it, and it is so thick set with prickles that it is almost impossible to touch it without being wounded. It is very prolific; almost half the year it is covered with flowers which produce pods filled with seeds. Besides it shoots out roots far and wide, from which suckers and young plants are continually springing up, which produce others in their turn. Where it is permitted to grow it soon overspreads whole tracts of ground, and it is extremely difficult to clear the ground of its roots where once it has got proper footing. Such provision has the just God made to fulfill the curse which he has pronounced on the earth, because of the crimes of its inhabitants. See Hale's Vegetable Statics.
