Electrical news and engineering . rom Riverton necessi-tated a great amount of tree cutting, and at many points itwas necessary to brace the poles by reason of the pole linegoing through muskegs. In digging the pole holes throughthese muskegs fourteen-inch Iwan post hole augers wereused to excellent advantage. By use of these augers thesoil is kept intact and the polo is immediately set before anyquantity of water fills in. THE ELECTRICAL NEWS A Street Lighting Time Switch that Allowsfor Seasonal Variation 111 tlio course of an address delivered by Mr. M. B. Hast-ings, of A. H. Winter Joyner, Ltd., before the recent con-vention of the at Niagara Falls on the subject ofModern Street Lighting. the speaker described a new de-velopment in an automatic time switch, specially designedfor turning street lights on and off at predetermined times. The ordinary automatic time switch has to be set period-ically according to the lighting schedule, which is regulatedby the varying seasons. The interesting point brought out. Season changing device by Mr. Hastings was tliat there is now availaldo what isknown as the Season Changing Device, for the .dersonelectrically operated switches. This device follows the sunand automatically controls the clock mechanism, so the lightsare turned on and off at the same time, relatively, through-out the whole year. The following details covering thisswitcli, taken frmn Mr. Hastings remarks, are of interest.— Wlioii tlie time switch leaves the factory, the season-changing device has been adjusted for correct operation atthe latitude where the switch is to be used, if known. Other-wise it is adjusted to the latitude of Boston—appro-ximatcly40 degrees north latitude. The latitude changing is done bylengthening or shortening of the cranks on the two smalldials A. This can be done by first loosening the centerscrews, when the cranks may be moved in or out, as adjustment is difficult to accomplish, and should not beattempted
