A Garage, Tennis Court, Skating Rink and Garden in One
ALFRED AUDET, a Salem, Mass., mar, L has constructed for his use a combi- nation garden, garage, tennis court and ice skating rink. This roof garden is built into the side of a hill in the rear of the dwelling. The hill was apparently a barrier to further development of the property, but it was eventually an ad- vantage. The garage space is hollowed out of the hill. The garage measures thirty-eight by seventy-seven feet and comprises six separate houses to accom- modate three cars each. Every compart- ment is thirteen by thirty-eight feet, with electric lights and hot water heating.
The dirt taken from the hill was placed on the roof of the garage for the tennis court and garden. Electric lights permit play at night. A wire netting thirteen feet high set in the large cement posts prevents balls from landing in the street below.
Besides the tennis court there is a spacious garden which makes a veritable bower of beauty. A pergola thirteen feet square and lighted by electricity is a feature of the garden.
The roof of the garage and the base of
��the tennis court and garden are of cement, ten inches thick. The whole makes a novelty in construction that is a delight to the many suburbanites who have seen it.
��Utilizing the Waste Heat from a] Gas-Engine
FOR a long time the waste steam from steam-engines has been turned to good account, but there have been diffi- culties in the way of using the exhaust gases from a gas-engine as they readily attack the metal of the conduits. How- ever, the difficulty is being overcome, for a New Jersey candy factory has an installa- tion in connection with a sixty horse- power engine which is used to heat the factory. The gases pass through an economizer made of cast-iron, with the passages to the different sections staggered so that all parts are heated for the whole length. Water circulates in jackets sur- rounding the gas passages.
