We are apt to think about water as free because Nature evidently intended that it should cost no more than fresh air. And so it is free, so long as we are satisfied to use very little, and to go and dip up that very little out of a stream and carry it to our homes. But when we demand the full fruits of modern civilization, when we insist upon the building of huge dams and vast reservoirs and tunnels and pumping-stations, we must buy the water they bring in order to pay for the cost of the convenience. What we pay in New York amounts to about $1.75 a head for every man, woman, and child in the city, or more than $3,000,000 a year. This great tax, called the "water rents," is used to pay the interest on the debt we owe for our aqueduct, to keep the system in repair, and to swell a sinking fund which we have established. The water rents are not paid according to the amount of water each person uses, but for the quantity that passes into each house, office building, factory, brewery, and stable. The house-owners each pay between four dollars and eighteen dollars a year, and the men who use great quantities--such as brewers, makers of mineral water, sugar refiners, and the like--in the course of their business all pay special rates, which seem very large indeed when we read the sums in print.

Grandmamma, who counts, perhaps, her threescore years and ten, sees a piece of faded calico, and her mind goes back to the time when, a little girl of eight, she was dressed in a new gown, of which this faded scrap is a remnant, and taken to town for "general training." She sees again the soldiers and the officers in their uniforms, she almost smells the cards of gingerbread, and hears the bustle and stir in the streets. She may not have thought of this special day for long, long years, but this bit of calico has brought it all back to her memory. Since the advent of cameras into nearly every family one has the opportunity of making actual pictures of festal occasions which occur, such as the birthday parties, the family picnics, John's new bicycle and his first unsuccessful attempt to ride it, the Hallowe'en frolic, the Christmas tree--any special day or event can be preserved in gelatine, and in a few years these pictures will have for one more interest and value than many made from much finer negatives. Now we want to suggest to our young amateurs that they start memory albums at once.
