If it be true, as our figures seem to prove, that a pound of food and a pint of drink are the average requirements for a full meal, then if an eating-house keeper offering meals for 10 cents could induce his customers to take a pound of bread, 3 cents, a pound of potatoes, 1 cent, a pound of mush, 1 cent and 3 cups of milk, 3 cents, for the three meals of one day his outlay would be 8 cents and his profit 22 cents; whereas if he should give a pound of meat, 10 cents, a pound of pie, 10 cents and a pound of syrup, but-er and batter cakes on one plate 10 cents, for the three meals of one day, he would have furnished no more than the average man could eat, would not have given a full meal and yet would have nothing left for profit. It is by striking a medium between these and not necessarily by using stuff that is unfit to eat that some men manage in every large city to sell meals for 10 cents ana make a profit. "Steak, bread, butter and potatoes, 10 cents," is what the sign boards announce. A pound of 8-cent meat, a pound of potatoes, 1 cent, a pound of bread, 3 cents - 3 pounds for the three meals of one day costing 12 cents out of 30 - add 3 pats of butter 1/2 ounce each - the regular restaurant size - 3 cmts more, and the eating-house keeper gives 15 cents and receives 30 cents, serves 300 meals a day and has 15 dollars a day margin out of which to pay his help, rent and wear and tear, etc., could afford even to add 3 cups of coffee to his sign-board inducements, while those who offer meals at 15 cents might afford to set a sumptuous table. There are hundreds of such places in operation : we are only seeking to know how they can do as they do. San Francisco, years ago, was talked about the world over as much on account of her having houses where a good meal could be obtained for 15 cents as for being the chief city of the Golden State.
