Show MAN AND HIS FOOD Tho The United S States s department nt o ot agriculture recently Issued a a. report showing that climate Is the principal j factor 1 In determining the varying 1 characteristics of ot wheat grown In cUt dlf- t terent ferent r regions glons The Tho bureau of ot chemistry chem had previously called attention to the fact that environment had more I Influence upon the crop than had th the tho composition of ot the seed And now flow these now new tests show that In environ meat ment climate plays a more important part than soil solL The source of ot all life the lire the sun sun eon contains con con- tame within It practically everything of or which this earth is composed and it is on the products of ot sunlight therefore there there- therefore fore tore that wo we have to depend for th tho 1 source of 01 all human energy ConversEly Con Con- it ft is logical then to look fo ro any absence of ot human energy or ha mony many In some lack of this universal driving power I Passing sunlight through a prism splits It into bands of ot color which we A know as the spectrum The sp spectrum is made up of ot six prominent hug hits supplemented by a multitude cf of subordinate sub sui ordinate ones the total number which the eye can recognize as distinct being not less than 1000 each one of which corresponds to a definite wave length of light and each probably producing somo some definite physical reactions o on similar substances At the red end of tho the spectrum we find tho the long waves and at the tho violet end we wo find the short waves and we have demonstrated that It Is the short rays at the tho violet end that act on the tho delicate silver salts while vegetation responds most to the yellow and red sections Tho The red end is known as the the heat or or rays and th the violet end as the chemical or actinic rays The green color cotor of ot the plant chlor bears some direct relation to the plants plant's ability to absorb the wave wavelength length needed to break brcak up the carbonic carbonic car car- bonic acid of the air and convert it into sugar starch and gums Excluded from tram light plants lose their color by br reason of the fact tact that this becomes submerged Into the protoplasm proto from which it came and from which it is again by exposure to light and heat seems to in in- dicato that vegetation normally growIng growing

lights That grown under red ted gla glass developed four times Umes as quickly as that grown under ordinary sunlight sunlight sun suu light shooting up like bean stalks Under green glass tho the result was not so striking yet the lettuce was taller than that produced in sunlight while that grown under the blue light was very Insignificant Other plants subject subjected sub sub- d to this

seriously disturbed tilt dis and modified by vibrations which cause It to move at a rate faster than that to which it Is adjusted and this is precisely what happens when single cells are exposed to the action of at the short rays and this Is why v violet vie vio let light radium emanations and the tho X x rays are fatal to 10 bacteria The The- protoplasm of ot our nerve cells Is la so very complex and unstable that It will wm not function except at the rate of ot vibration between 98 and degrees Fahrenheit though a temperature or of of degrees may require somo days days' to break up the
