The Chicago 'Iriluns réstales its theory ou th is subject as fullowa : 1. Tho preBeuce of mm spots this year causes an averago reduction f tibout iwo degrees of Fabrer.heit'in the amount of heat eupplied to the cartli by ihe sun. 2. The npcessarj effect of this will be a diminished ovapnratioi) from the ocean and tina will be evidout iu a lesscned ruin-1'ull on tlie land, 3. About two fiftlis of all tho heat received by the earth fro:n tlio suo ie earried off by evaporation, 972 degrecs of lr.'at bcing rondorüd la;et o thu oonversión of water into vapor. itti a small rain-full, vcry.little caloi o ie curried ctl in tliis way, and a mueh largor ptopurtinn ol tho salar beat than ucnal ia retuioeil in thu ground, and remaioi in the lower slrata of tho atmosplioio.
