The local inc が ase of uo り I’ishm 別 it in young ‘shoots of Pinus can be 
easily effected in springti me in the early stages of their (:] eveiopmeut ; 
fkstly, by po り arding the shoots and tlu け inducing all the nourishment 
in が ore to l)e used in the development of the remaining poi*tions of the 
shoot, especially the flow が s and 。 技 vn.ztriehe ’’ nearest the wound ; 
secondly, by keeping only one or two and breaking off all the other 
adjacent young shoots at the top of the last year’s shoot ; thirdly, by 
combining these two pi’oces がん 
By ap が yjug these processes I have succeeded in some measure in 
producing female and Iwi'inapiirodite flowers which would o り、 erwi 只い 
grow into male flowers. It was on April 30fch 1895, in the Botanic 
Garden of tlie Imperial University, that the polhmling : for my researches 
was done on two young trees of Pinus densijicn'a, whose shoots of tho 
last year were left uninjured bj the garden がぶ. At that time tlie 
" Anlagen ，， of the 月 owei.s were already apparent in every : feirtile 
shoot. The pollardi 打 g in Lotli trees was done at random, but it was 
found afterwards that the branches whose shoots w げ e cut off had iio 
traces of any previous injuri が. The effects of 卜〇ルげが〇谷' were chiefly 
examined in the beginning of M((iy and later on, and also on Jnly
