There is, perhaps, nothing new in this method of feeding cattle with liquid mixtures, but the manner in which these drinks are now prepared in Germany is, I believe, quite new; and shows what I wish to prove, that COOKING RENDERS FOOD REALLY MORE NUTRITIVE. These drinks were formerly given cold, but it was afterwards discovered that they were more nourishing when given warm; and of late their preparation is, in many places, become a very regular culinary process. Kitchens have been built, and large boilers provided and fitted up, merely for cooking for the cattle in the stables; and I have been assured by many very intelligent farmers, who have adopted this new mode of feeding, (and have also found by my own experience,) that it is very advantageous indeed; that the drinks are evidently rendered much more nourishing and wholesome by being boiled; and that the expence of fuel, and the trouble attending this process, are amply compensated by the advantages derived from the improvement of the Food. We even find it advantageous to continue the boiling a considerable time, two or three hours, for instance; as the Food goes on to be still farther improved, the longer the boiling is continued[3]. These facts seem evidently to show, that there is some very important secret with regard to nutrition, which has not been yet properly investigated; and it seems to me to be more probable, that the numbers of inhabitants who may be supported in any country, upon its internal produce, depends almost as much upon the state of THE ART OF COOKERY, as upon that of agriculture. --The Chinese, perhaps, understand both these arts better than any other nation.--Savages understand neither of them. But, if cookery be of so much importance, it certainly deserves to be studied with the greatest care; and it ought particularly to be attended to in times of general alarm on account of a scarcity of provisions; for the relief which may in such cases be derived from it, is immediate and effectual, while all other resources are distant and uncertain. I am aware of the difficulties which always attend the introduction of measures calculated to produce and remarkable change in the customs and habits of mankind; and there is perhaps no change more difficult to effect, than that which would be necessary in order to make any considerable saving in the consumption of those articles commonly used as Food; but still, I am of opinion, that such a change might, with proper management, be brought about. There was a time, no doubt, when an aversion to potatoes was as general, and as strong, in Great Britain, and even in Ireland, as it is now in some parts of Bavaria; but this prejudice has been got over; and I am persuaded, that any national prejudice, however deeply rooted, may be overcome, provided proper means be used for that purpose, and time allowed for their operation.
