 At Hyde Park, Mass, there has re- gently been finished the first solar motor in this part of the country.
 For several months the residents Of the town have been watching with great deal of interest the construction of this piece of clever and unique mechanism which is entirely new to this part Of the country. The machine as 1t now stands is. ncth7 ing more or less than an immense solar motor. The motor, which looms up In the distance like a Ferris wheel on reduced scale, has been in actual work ing order for few weeks. and by means of the powerful heat rays reflect cd from its heat battery of flashing mir TOTS, its builders have been enabled to small sawmill. . ~ Since the coal famine wood has un- doubtedly been sawed in this part of the country in many ways, but this is the first time such . feat has ever been ac- complished through the indirect action of the sun.
 The motor consists of an immense con- cave reflector, mounted on two towers or iron, the rear one about thirty-six feet from the ground and the front one about eight. The top rim of the. reflector Is
 
 and has diameter of thirty-six feet on the outside and. narrows to a diameter of eighteen feet five inches on the in side,. or bottom. It is lined with 360 mir TOTS made by German process and backed with wire netting cloth. These mirrors are arranged in six horizontal rows, and the rays of the sun are re- fected by them upon q large boiler, sup ported in the center of the reflector. This 1tkr, 1E nLa f.,fw l. lons is fed by an automatic pump and is tested to 200 pounds to the square inch. It weighs about eight tons and is of pe- culiar construction. the lower part be- ing composed of a series of three cop per coils, upon which the heat rays con centrate. To prevent radiation and pro- tect them from the action of the wind, these coils are covered. by an isinglass jacket. It is so arranged that the infiu- ence of the six rows of mirrors is evenly distributed among the coils, two rows concentrating upon each one of them.
 In recent test made upon a bright day, which was not. however, especially warm, the 1,200 square feet of mirrors when squarely exposed to the action of the sun. produced an intensity of heat equal to .1,2O2 degrees Fahrenheit, and caused the boiler to blow off at 200 pounds. Those in charge of this unique and pow erIul natural neat cOllectOr are comment that even a greater degree of caloric can be generated. The depth of the reflector from top to bottom is about ten feet. Steel wire braces and steel spokes span 1t in sort of network to keep it firm. One of the most interesting features of the machine is the automatic electric clockwork which keeps the reflector con- tinually in focus with the sun. This au- tomatic scheme works on about, the same principle which keeps many of the large telescopes in focus.
 The building of this solar motor was started June IT, 1902 and now that 1t has been tried out and proven a success. it Is soon to be sent away to California and work has already been started upon several others. .,..
 To J. M. Burns Of Canton. who has had charge of the construction, of the motor, is due much credit, and he is very well pleased with the results .oThe one now at Hyde Park is about 1fteen fhorse power, which can be generated at prac- tically no expense, save that -af sattsna- ance. Water for; steam is cheap and Old Sol does the rest, . .. .,,t.
