We are forced to conclude, in the face of all the available evidence, that the natural constitution of man closely resembles that of fruit-eating animals, and widely differs from that of flesh-eating animals, and that from analogy it is only reasonable to suppose that the fruitarian, or vegetarian, as it is commonly called, is the diet best suited to man. This conclusion has been arrived at by many distinguished men of science, among whom are the above mentioned. But the proof of the pudding is in the eating, and to prove that the vegetarian is the most hygienic diet, we must examine the physical conditions of those nations and individuals who have lived, and do live, upon this diet. It might be mentioned, parenthetically, that among animals, the herbivora are as strong physically as any species of carnivora. The most laborious work of the world is performed by oxen, horses, mules, camels, elephants, all vegetable-feeding animals. What animal possesses the enormous strength of the herbivorous rhinoceros, who, travellers relate, uproots trees and grinds whole trunks to powder? Again, the frugivorous orang-outang is said to be more than a match for the African lion. Comparing herbivora and carnivora from this point of view Dr. Kingsford writes: 'The carnivora, indeed, possess one salient and terrible quality, ferocity, allied to thirst for blood; but power, endurance, courage, and intelligent capacity for toil belong to those animals who alone, since the world has had a history, have been associated with the fortunes, the conquests, and the achievements of men.' Charles Darwin, reverenced by all educated people as a scientist of the most keen and accurate observation, wrote in his _Voyage of the Beagle_, the following with regard to the Chilian miners, who, he tells us, live in the cold and high regions of the Andes: 'The labouring class work very hard. They have little time allowed for their meals, and during summer and winter, they begin when it is light and leave off at dusk. They are paid L1 sterling a month and their food is given them: this, for breakfast, consists of sixteen figs and two small loaves of bread; for dinner, boiled beans; for supper, broken roasted wheat-grain. They scarcely ever taste meat.' This is as good as saying that the strongest men in the world, performing the most arduous work, and living in an exhilarating climate, are practically strict vegetarians.
