Largest Airship to Be Com- pleted, Longest Bridge Begun-Secrets of Cave man May Be Revealed Heat From Sun Sought.

Bridge, telescope, dam and airship all larger and better than ever built before.
 Better health and less deaths. Progress toward the rescue Of hu- mankind from an eventual death due 10 lack Of power. More knowledge of the human past and moro plans for tho human future.
 These stand out in sciences calen- dar for achievement in 1881.
 Utilization of sun power may ap- proach closer solution.
 Direct use ot the suns rays for power will become a stark necessity ryhen the stored supplies Of fossil 1 fuel, coal and oil, are exhausted. Science must look forward and make u continuous supply Of energy safe tor the human beings Of hundreds Of years hence.
 For this reason there is quiet re- search in laboratories on the prob- loms Of turning light and heat rays efficiently into electricity. The sun is being studied intensivcly. Engi- noes arc attempting 10 develop ! practical methods of deriving power from the difference Of temperature i in sea water and the tides. | To Convert Light Into Electricity
 The practical conversion Of light into electricity is already tho basis of large industry, talking motion pictures. l. promises 10 be funda- mental in another industry, tele- vision The photoelectric cell nicknamed the "rlectric cye," pro- i duCes an electric current when light tails upon il. But the conversion ] process is inefficient from the stand point ot power production. \ power photoelcctric cell that will equal or exceed even the low efficiency of the familiar steam or internal combus- ] ton engine is needed.
 l Experiments are being mad- quietly. In Germany, q copper oxide cell has produced relatively lar@" amounts Of electricity from the { effect Of light falling upon it In Germany coal is being liqui- fed into motor fuel 10 such an eX- tent that gasoline imports have been greatly reduced The coming year will probably see an extension 0, 1 hydroEcnation of hydrocarbons in i This country while other chemical I processes will come 10 perfection and . m oG1tv .NiCtIUg- ju1nG-rlaS
 l Half Million Volt Power Lines The construction Of the BOulder dam, which will begin in earnest during 1881, will give impetus tc now methods for the transmission ot electricity. Already there are . laboratories for the creation of ovct a million volts of electricity for tho 1 purpose ot testing insulators, etc. and soon there will be transmission lines operating at yollaees ot nearly half million.
 1 High voltaga electricity promise. 10 aid the physicist in his eXplora. tons ot the atom and its nucleus Attacks upon the heart Of chemICa dement's are being planned. I'm. mcuse vacuum or N-ray tubes arr being built or new devices arc being developed 10 Lombard the in ner portion of the atom with sucl power that its secrets will be un locked.
 Further progress upon the con struction of the -6Q-inch telescope 10 be twice as large as the world largest now at Mt. Wilson in Cali Iornia, will be made during 1881 And on some as yet unchosen noun tain peak in California, the observa
 tory site will he prepared.
