In any given semester the number of students in one of these corps varies from as few as ten, to as many as twenty-five, depending, much as do our Greek-letter societies and college clubs, upon the number of available men coming up to the university. Certain corps are composed almost exclusively of noblemen, but none is distinctly a rich man's club. An active member of a corps during his first two semesters may do a certain amount of serious work, but as a rule it is looked upon as a time "to loaf and invite one's soul," and little attempt is made to do more. Not a few men whom I have known, have not even entered a class-room during the two or three semesters of this blossoming period. I have spent many days and nights with these young gentlemen, at Heidelberg, at Leipsic, at Marburg, at Bonn, and been made one of them in their jollity and good-fellowship, and I have agreed, and still agree, that "Wir sind die Koenige der Welt, wir sind's durch unsere Freude." They are by no means the swashbuckling, bullying, dissolute companions painted by those who know nothing about them. They may drink more beer than we deem necessary for health, or even for comfort; and they may take their exercise with a form of sword practice that we do not esteem, they may be proud of the scars of these imitation duels, but these are all matters of tradition and taste. When one writes of eating and drinking, it is hardly fair to make comparisons from a personal stand-point. An adult of average weight requires each day 125 grams of proteid or building material, 500 grams of carbohydrates, 50 grams of fat. This equals, in common parlance, one pound of bread, one-half pound of meat, one-quarter pound of fat, one pound of potatoes, one-half pint of milk, one-quarter pound of eggs, assuming that one egg equals two ounces, and one-eighth pound of cheese. Divided into three meals, this means: for breakfast, two slices of bread and butter and two eggs; for dinner: one plateful potato soup, large helping of meat with fat, four moderate-sized potatoes, one slice bread and butter; for tea: one glass of milk and two slices of bread and butter; for supper: two slices of bread and butter and two ounces of cheese. Plain white bread supplies more caloric, or energy, for the price than any other one food, and, with one or two exceptions, more proteid, or building material, than any other one food.
