332 ScJiively — Contributions to the Life History of 



four compound leaves, and in the axil of each a small branch 

 having minute buds. Beyond the last leaf was a shoot 

 9 inches long, bearing three buds. 



On March 14, the shoot was 32 inches long, and there 

 was a very slight increase in size of buds. 



On March 21, the length of shoot was 32^ inches. 

 From the axils of the second and third leaves there were two 

 axillary buds each. That from the fourth leaf had two tiny 

 flat green legumes 3/q inch long. Upon the terminal portion, 

 pod 1 was Y% inch long, 2, ^\ inch, 3, % inch long ; all 

 were still rather flat. 



These and similar notes seem to indicate that the matur- 

 ing of the terrestrial legume is comparatively rapid. In 

 the second, certainly the third week, after fertilization, they 

 assume good proportions. After this, the increase is very 

 steady, and growth would be likely to continue during the 

 life of the plant, though the seed is probably mature early. 



Then came the question : Will shoots from other leaves 

 than this first green pair, produce these subterranean 

 legumes? 



On July 23, shoots from simple leaves, also from first, 

 second, third, and fourth compound leaves were buried in 

 separate pots. All were long, bore leaves, but as yet 

 showed no indication of flower buds. 



Circumstances prevented examination until September 

 3. Finally all were removed September 25. Every one of 

 the shoots had branched extensively both inside and out- 

 side of the pots. The tips which were thin and green 

 when placed in position had thickened, formed, even roots 

 had developed. Legumes of all sizes were here ; well- 

 developed ones one-half to three-quarters of an inch long 

 were taken from each pot, in number from two to six; 

 while smaller ones were numerous. In regard to produc- 

 tiveness of axillary shoots, those from simple leaves gave 

 the greatest yield ; those from compound leaves differed 

 little in fruitfulness ; not one failed to develop some.
