be connected with the plumbing if desired. When not in use the machine forms 

 a table surface by means of a hinged cover. Two kilowatt-hours per month is 

 regularly used for washing the dishes three times a day. 



Farm No. 6. This washer is circular in shape and contains two racks, one 

 above the other, for holding the dishes. The washing action is satisfactory, but 

 the housewife feels that she can handle the dishes in the dishpan with the same 

 amount of effort and does not have to take care of the washer after the opera- 

 tion is over. Use of the machine has been discontinued. 



The development of a dishwasher which will meet general approval in prac- 

 tical use is of great interest to the farm housewife because of the quantity of 

 dishes handled. The failure to handle pots, pans and kettles is the most common 

 disadvantage mentioned. The quantity of water required is important, and the 

 propeller washing action is very effective. 



Successful operation appears to involve the size and shape of the machine and 

 the rack for holding the dishes. One single rack of large capacity is desirable. 



Kitchen Ventilating Fans. One such device is in use and is found to be very 

 effective in removing cooking odors, steam and gases from the kitchen. Fans are 

 generally furnished mounted on a panel which is easily attached to a window in 

 such a way that the sash may be opened or closed as desired. Records of cur- 

 rent consumption and use will be available. 



Electric Water Heaters. Results obtained from the use of electric water 

 heaters emphasize the need of consideration from two distinct angles: (1) the 

 degree of mechanical and electrical efficiency of the heater itself; and (2) the 

 cost of operation. It appears now that the latter point is the limiting factor to 

 their adoption and successful use. 



The heaters in use in the experiment have given, without exception, a very 

 high grade service. The only difficulty experienced during the past season was 

 one case of a loose connection — a fault of installation. 



Farm No. 1. This complete unit consists of a 15-gallon insulated tank with 

 automatic and manual current control, so that a continuous supply may be main-

tained or water may be heated as needed. The equipment is located in the bath- 

 room, and furnishes hot water also for the kitchen a short distance away. Water 

 is heated only as needed during the week, and on days when a large amount of 

 water is used is heated automatically. No other water heater is used. 



Farm No. 3. A circulation type healer is attached to the original 30 gallon, 

 uninsulated range boiler, and is used only as an auxiliary, for emergency or in 

 the warm summer months. Insulation of the tank was omitted because of its 

 constant exposure to the heat of the range. The bulk of the hot water used dur- 

 ing the year is heated from a coil in the firebox of the combination range. Water 

 is supplied to the kitchen and bath. The current is turned on and off by hand. 



Farm No. 4. A circulation-type heater is attached to a 30-gallon range boiler 

 which furnishes water to the kitchen only. The boiler has been uninsulated for 

 the past season due to its close proximity to the firebox of the combination range. 

 The electric heater is used mostly during the summer months and in emergencies. 

 The current is turned on and off manually, for the most part, to reduce the cost 

 of operation.
