In recapitulating the food supplies of the Seri it is not without interest to estimate roughly the relative quantities of the several constituents consumed; and the proportions maybe made the more readily comprehensible by expression in absolute terms. As a basis for the quantitative estimate, it may be assumed that the average Seri, living, as he does, a vigorous outdoor life, consuming, as he does, a diet of less average nutrition than the selected and cooked foods of higher culture, and attaining, as he does, an exceptional stature and strength, eats something more than the average ration; so that his ration of solid food may be lumped at 2.75 pounds (about 1,250 grams) daily, or 1,000 pounds (about 455 kilograms) yearly. The aggregate diet of the tribe may be estimated also by assuming the population to comprise 300 full eaters, besides, say, 50 nurslings negligible in the computation; so that the annual consumption of the tribe may be reckoned at 300,000 pounds (136,000 kilograms), or 150 tons, of solid food. Accordingly the several constituents may be estimated, as shown in the accompanying table, in percentages of the total, in pounds aggregate and apiece for the eaters, and (so far as practicable) in units both aggregate and apiece; the weights of units being roughly averaged at 100 pounds (45 kilograms) for turtles, 12½ pounds (5.6 kilograms) for large land game, 450 pounds (about 200 kilograms) for stock, and 2 ounces (56.7 grams) for tunas. _Estimated annual dietary of the Seri tribe_ Constituents Per Quantity Units cent Aggregate Apiece Aggregate Apiece _Pounds_ _Pounds_ Turtles 25 75,000 250 750 2½ Pelicans 5 15,000 50 1,200 4 Other water-fowl and eggs 8 24,000 80 Fish 15 45,000 150 Shellfish (except turtles) 10 30,000 100 Large land game 7 21,000 70 200 ⅔ Other land game 8 24,000 80 Stock 6 18,000 60 40 2/15 Tunas 9 27,000 90 216,000 720 Other vegetals 5 15,000 50 Miscellaneous 2 6,000 20 Total 100 300,000 1,000
