in the enterprise, their inspection was official in that their report indicates the interest taken in it by one of the largest developing corporations in the country.
 The secretary and treasurer of the company is c. L. Haskell, who has been here for sometime experimenting the construction of this motor and from him a good description of it and of the company's operations was se cured. Mr. Haskell says that though | the company has spent $125,000 in it's | operations of the last nine years, it has claimed the successful operation of the motor for only three years past. Previous to that time it was largely an , experimental enterprise and frequent Improvements were made in the mech anism but for the last three years the motor at Pasadena which was the first really successful one built, has been in continuous operation. But the com pany did not care to put it upon the market till it had been fully tested and could be legitimately guaranteed. So far all the machines. constructed have been manufactured in Massachusetts. The capacity of the Tempe motor is about six horse power and though they can be made any size, the sizes will probably run from five horse power up to six or eight horsepower. Within each motor is the boiler where steam 1 is generated, and carried by a pipe to | the engine. Where a large plant is de- sirable it is thought better to have ad- ditional motors, each connected with the engine by a steam pipe, rather than to have one immense motor as large as two or more smaller ones.
 The motor as everyone will under stand, is dependent on sunlight for power and it is therefore obvious that it would be incompetent on a rainy day and also for such purposes as require power day and night, but for any en- terprise where absolutely continuous power is not necessary, such as pump ing for irrigation, it seems to be the acme of success for it eliminates en- tirely the fuel expense. Mir Haskell said that in any country where the weather is seventy-ffve yer cent sun shine and not to exceed fifty per cent humidity, it may be successfully op- erated Roughly speaking, it is avail able for use over about one half the surface of the earth and in this country nearly everywhere west of the 97th
 
 rise il will generate 15O pounds of steam and the accumulated power will last till a half hour after sunset The motor does not depend upon the light rays of the sun. but upon the heat rays, and it is therefore just as good in winter as in summer, providing it is ! clear.
 The reflector is in shape very similar to milk pan with the bottom out. only that the diameter of a milk pan is greater in proportion to the depth of the pan, than is the diameter of the motor in proportion to the depth of it's l sides. In the Tempe machine the di- ameter of the reflector on the side to- l ward the sun is 36 feet and on the bet l tom side IS feet. Along the margin, or | what would be called the side were it a milk pan, are the rehectors consist ] ing of TIPS small glasses covered on the back with three coats of pure silvers 1 This reflector is supported between two l towers, one about 30 feet high and the other about : feet high, which sus- bends it at an angle.
 The reflector must face the sun ex- actly, and as heavy as it is, weighing tons, it can @be easily moved It stands. after the fashion of the telescope, up- on an equatorial mounting, the axis being north and south; the reflector follows the sun, regulated by a clock the work being automatic, as, in fact, is everything about it. The true focus is shown by an indicator, and in about an hour after it is adjusted the boiler is seen to have attained a white heat and the steam gauge registers one hundred and fifty pounds. The steam fc- rloI the engine in a flexible phosphor- bronze tube and returns again from the condense~ to the boiler in the form of water, so that the boiler is kept au- tomatically full. The engine is oiled automatically. and when the disk is Tonce turned facing the sun, it runs all day as Independent of an engineer as does windmill:
 The amount of heat concentrated in ! the boiler by the seventeen hundred | and odd mirrors cannot be realized, as nothing can be seen but small cloud of escaping steam, but should a man climb upon the disk and cross it he would literally be burned to a crisp in a few seconds.
 The boiler eight feet long, is sus- pended in the center of the reflector, as lead pencil would be suspended perpendicularly in a bottomless milk pan. The reflected heat therefore ! strikes it all over except on the ends. | The steam is carried from the top of boiler, through a small pipe to the en- zine and after use passes through a condenser and "a small pipe back into | the boiler at the other end. The en- zine, pump, etc, is the same as in any other plant.
 The motor at Tempe has probably been sold for later erection at Wilcox, but in any event 1t will be there on ex- hibition for the next two weeks under the care of J. Murdo Bruns, and Cliff ford s. Estes, engineers, who will take pleasure in showing it to any visitor. ! The Solar Motor Go. put up it's first successful motor on the property of
