kitchen until it is set and the meal is 

 ready. It can then be brought into the 

 living room at the time the walls are be- 

 ing turned. The different courses are 

 kept in drawers until needed. The same 

 drawers are used for keeping the soiled 

 dishes until they are washed. At the con- 

 clusion of the meal, the walls are again 

 turned and the table and dishes auto- 

 matically placed in the kitchen. 



Aside from the foregoing features 

 there are many other less prominent in- 

 novations incorporated in the house. 

 The heating system is quite remarkable 

 and can be operated very economically. 

 While the bungalow offers every possible 

 comfort, it is so cleverly designed that its 

 upkeep is within the means of those with 

 moderate incomes. 



TINY ELECTRIC TRUCKS HANDLE 

 HEAVY EXPOSITION FREIGHT 



The heavy freight at the Exposition 

 grounds in San Francisco, such as ma- 

 chinery, displays of manufactured arti- 

 cles, furniture, and cases of foreign ex- 

 hibits, has all been handled by ten small 

 but powerful electric trucks. These 

 trucks are operated from the rear end, 

 one man usually serving both as driver 

 and unloader, and not only extremely 

 heavy loads, but remarkably fast time 

 has characterized this manner of hand- 

 ling the freight. Five to eight hundred 

 tons daily has been the capacity of this 

 unique system of distributing the incom- 

 ing exhibits from the steamers and trains 

 to the exhibit palaces and state and na- 

 tional buildings. The accompanying il- 

 lustration shows one of these electric 

 trucks carrying a large and heavy log 

 up an incline to the exhibit of the State 

 of Washington, which is in the Agri- 

 culture Building. The trucks handled 

 nine carloads of these logs in 131/2 hours. 



This illustrates the efficiency of modern 

 methods of freight distribution by a sys- 

 tem of trucks which take up very little 

 room and can go through small spaces. 



FLAMELESS HEAT 



It is reported that an English scientist 

 and investigator has hit upon a manner 

 of gas heating that may greatly change 

 our methods of using fuel. When a 

 mixture of gas and air under high pres- 

 sure is directed against a red-hot fire- 

 brick held a short distance away, the 

 mixture will burn at the surface of the 

 brick. Now, if such a mixture of gas 

 and air is forced through the porous 

 brick, and lighted on the farther side, it 

 will burn like an ordinary gas flame; 

 but if more air or less gas is used, it 

 ceases to burn, but the porous surface 

 becomes white hot. In that way it is 

 possible, with great economy of fuel, to 

 get a temperature far above the melting 

 point of platinum. This flameless heater 

 has been used for heating boilers. 

 It is claimed that it will do away 

 with grates, smokestacks and 

 chimneys, that it produces no 

 smoke or objectionable odor, and 

 that it utilizes 90 per cent, of the 

 heat value of the fuel. 



Ten Small Storage Battery Trucks Have Been Handling the 

 Heavy Freight at the Exposition Grounds. 



A Pennsylvania electric power 

 company is contemplating the in- 

 stallation of wireless telephones 

 for insuring communication be- 

 tween their power houses and 

 substations at all times. These 

 scattered points are now joined 

 by regular telephone, and the 

 radio sets are to be used in 

 emergencies.
