been brought under the control ofthe chemist,consequently it lacksflexibility in the adaptation of itsproducts and it loses heavily fromwaste.  \nI venture as my first forecast thatthe farmer of the future will stop,toa large extent,raising field crops assuch.  He will raise raw materials.He will aim to produce carbohydrates,fatty acids,amino-acids and hetero-cyclic compounds,rather than raisesugar beets,cotton seed,beef and to-bacco.He will employ whateverplants will give,in his locality,thelargest yield at the lowest cost of theparticular class of chemical com-pounds that are most in demand atthe time.  \nThe farmer of the future will notconfine himself so largely as in thepast to the production of foods.Forthere is a limit to this market.Weought not to eat any more than wedo and we ought not to waste as muchas we do.Even if the highways arelined with illuminated billboards be-seeching or commanding us to\"Eatmore wheat”,“Eat more raisins”,\"Eat more apples”,\"Eat more pota-toes”,and“Eat more peanuts”,wecannot follow all this gratuitous ad-vice.My grandfather used to say tome when I overloaded my plate withsome food I liked:\"My boy,youreye is bigger than your stomach.”But that is only true of eating.Ourstomach for automobiles,radios,silkstockings and newspapers seems in-satiable.Therefore,the farmer longsto get out of food production andinto a field where the opportunity forhigh-powered salesmanship is unlim-ited.  \nI have never been one of thosechemists,like Berthelot,who foresee  \nScience New8-Letter,December 1,1928  \nNTERPRETING week by week,the latest developments in thevarious fields of science,this magazineattempts also to present its articlesin the most pleasing and readabletypography and the most convenientarrangement.  \nIn This Issue—  \nAn argument against the next war,p.333—Freeing the world from bond-age,p.335—Color snapshots,p.337一Millions of Indians,p.337—Secretsof Rubber,p.339—Knockless fuel,p.341—Electrons and protons,p.341—Inflammable air,p.343—New books,p.346.
