The third table comprehends those quadrupeds only which are domestic in both countries. That some of these, in some parts of America, have become less than their original stock, is doubtless true; and the reason is very obvious. In a thinly-peopled country, the spontaneous productions of the forests, and waste fields, are sufficient to support indifferently the domestic animals of the farmer, with a very little aid from him, in the severest and scarcest season. He therefore finds it more convenient to receive them from the hand of nature in that indifferent state, than to keep up their size by a care and nourishment which would cost him much labor. If, on this low fare, these animals dwindle, it is no more than they do in those parts of Europe where the poverty of the soil, or the poverty of the owner, reduces them to the same scanty subsistence. It is the uniform effect of one and the same cause, whether acting on this or that side of the globe. It would be erring, therefore, against this rule of philosophy, which teaches us to ascribe like effects to like causes, should we impute this diminution of size in America to any imbecility or want of uniformity in the operations of nature. It may be affirmed with truth, that, in those countries, and with those individuals in America, where necessity or curiosity has produced equal attention, as in Europe, to the nourishment of animals, the horses, cattle, sheep, and hogs, of the one continent are as large as those of the other. There are particular instances, well attested, where individuals of this country have imported good breeders from England, and have improved their size by care in the course of some years. To make a fair comparison between the two countries, it will not answer to bring together animals of what might be deemed the middle or ordinary size of then species; because an error in judging of that middle or ordinary size, would vary the result of the comparison. Thus Mons. D'Aubenton[27] considers a horse of 4 feet five inches high and 400 lb. weight French, equal to 4 feet 8.6 inches and 436 lb. English, as a middle-sized horse. Such a one is deemed a small horse in America. The extremes must therefore be resorted to. The same anatomist[28] dissected a horse of 5 feet 9 inches height, French measure, equal to 6 feet 1.7 English. This is near 6 inches higher than any horse I have seen; and could it be supposed that I had seen the largest horses in America, the conclusion would be, that ours have diminished, or that we have bred from a smaller stock. In Connecticut and Rhode Island, where the climate is favorable to the production of grass, bullocks have been slaughtered which weighed 2,500, 2,200, and 2,100 lbs. nett; and those of 1,800 lbs. have been frequent. I have seen a hog[29] weigh 1,050 lbs. after the blood, bowels, and hair had been taken from him. Before he was killed, an attempt was made to weigh him with a pair of steel yards, graduated to 1,200 lbs., but he weighed more.
