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.
