month six slender, shining parallel veined linear leaves were waving 

 gracefully above the soil. I let them grow in the hot sun until the 

 ist. of September, then I carefully removed the earth from around them 

 and put them in a glass jar. The method of germination is illustrated 

 in Plate A, Fig. 2. 



In every case the radicle had come from the smooth side, even 

 when it had to make quite a curve in order to turn its point into deep 

 soil and the plumule springing from the convexity of the radicle 

 starts upward. Thus proving that the germination is invariably the 

 same, always rising from the center of the back of the seed and send- 

 ing forth at the same time two growths, one downward, termmating in 

 roots and rootlets, and the other upward, forming the leaf and eventu- 

 ally the tree proper. Mrs. J. E. DixsoN.

 sketch after Sachs' diagram, of the cross section of the date seed I, and germ- 

 ination of the same, II and III, showing internal arrangement of plumule, cS:c.)
