Bf For a long tlmo tho roots of plnnts BVB ; havo boon studied, ami the longer tho BV u study 'Is carried on, thu moro surprls- BBJ j iK aro tho results. All tho theories BVB I as to how plants should root havo BVB , boen destroyed by tho actual facts H being brought to light. Thus, It has BVB ncen nqsumed that plants that boar BV pods and arc assisted by tubercles B on tho roots to gather nitrogen from BVB , tho air would bo rather shallow root BV ers, but would havo a largo root SBm system. On Investigation, wo And BS that this Is tmo In somo plants nnd Bfl ( not truo In others. There seems to BVB j ho as great a divergence of processes BBJ of rooting In tho legumlnosao family BBf as In any others. Thus tho alfalfa BY plant sends down Its roots to an lm- BY menso dopth, sometimes SO and even BVB 0 feet. Tho clover root also goos Bfl deeply, often 3 and 4 foot, whllo cow Bb peas nnd Boy beans havo very small BH ' root systems. Tho clover will havo BH :- thrco times tho nmount of root thnt a BH cow pea of tho samo volumo will havo. BS Whon corn plants wero dug up, all BS ' the roots being saved, It was found HB that they had n surprising volumo of BS roots. Corn hns always been consld- BB I ercd a surfaco rootor. It Bonds out Bg ' Its roots near tho surface and It wns BS known thnt It sent down other roots BS as far as tho depth of tho plowed soil, BS gonornlly soven or eight Inches.
