bears upon this question of cutting the tubers for seeds, and that is 

 that there is a system of roots, imperceptible ordinarily to the 

 naked eye, but discoverable by a chemical process, extending from 

 the eye down to the center of the tuber, and the inference from this 

 discovery is that in cutting for seed you prune these roots too 

 much if you do not cut down to the center of the tuber instead of 

 a lateral cut, as is usually done. Hiram Sibley & Co., seedsmen 

 of Rochester, New York, have a picture in their catalogue this 

 year, showing how to cut a potato with reference to Prof. Sturte- 

 vant's discovery, and I will ask them to furnish the cut of it to 

 illustrate this discussion in our next report. 



(The cut has been kindly furnished by Messrs. H. S. & Co., and 

 is herewith reprinted).
