Choose the place for your net so as to give an equal space behind each base-line. Measure 36 feet, and put in a peg at either end, with the tape-line fastened to it. Take 39 feet on one measure, and 53 feet ¾ inch on the other. Where they cross is one corner. Mark off 21 feet from the net from one end of the service-line. Transpose the measures and do the same thing, and you have half the court. Carry the measures to the other side of the court, and repeat the operation. The central-line runs from the middle of each service-line. The inner side-lines run from base-line to base-line 4 feet 6 inches inside of the side-lines. If you are marking out a double court only, do not carry the inner side-lines beyond the service-lines. Make a mark inside the middle of the base-line to show where the server may stand. The diagonal of a single court is about 47 feet 5 inches. If possible, have the court run north and south.
The New Mint Building.
The old United States Mint, for so many years in the crowded and expensive neighborhood on Chestnut Street in this city, is to be torn down and removed to Spring Garden and Sixteenth streets, about one mile north of its present location. Strong efforts were made to get the Mint removed to Washington when it was found necessary to build a new one. Even Chicago and New York tried to get it away from here. But five years ago a whole square was purchased for its site, and Philadelphia breathed easier.
The new Mint will have a main entrance on Spring Garden Street. It will be in the form of a hollow square, giving a court-yard open to the sky. It is to have a terrace balustrade constructed of granite. Above it the material will be marble. The style is severely plain classic, and the design as shown on paper is far from pleasing. In the plan is provided a spacious room for the coin museum, which many readers have doubtless seen in the old building. It is by far the finest collection of old coins in the world, outside of the British Museum. Work upon the new Mint building is expected to begin next spring.

Answer to Convent Puzzle.
By looking at these four diagrams you will see the trick of the puzzle. Fig. 1 shows the nuns on good behavior; Fig. 2, when four sisters have escaped; Fig. 3, when they have returned with four friends; Fig. 4, when four more outsiders have been admitted—presumably by a rope-ladder.
