The most fundamental of all the factors which contribute to success in any enterprise is health, and the primary factor in making a faultless organism, either human or animal, is the diet. It is not permissible to attribute the differences observed between the Bahamans and Canadians solely to climate, for their diet has been so different that there is good reason to suspect that the attitude toward work and mental effort in the two groups is in no small measure due to the way they feel. Our knowledge of the effects of an unsatisfactorily constituted diet, warrants us in attributing their characteristics to this cause. The Bahamas produce tamarinds, olives, lemons, oranges, limes, citrons, pineapples, pomegranates, figs, sapodillas, bananas, melons, yams, potatoes, cucumbers, cassiva, sugar, maize and peas as the chief edible articles. From what has been said this list of storage tissues of plants is not likely to promote health. Their bread-stuff and meats are imported from the United States. The people of Lower Canada have, on the other hand, a diet much like that of the United States, viz.: one into which a considerable amount of dairy products enters regularly. It consists principally of cereals, legume seeds, tubers and meats, but milk, butter, cheese and cream are regular components. People will feel very differently on these two types of diet.
