ospores were sown on two unidentified species of Castilleja and produced

In Europe several papers on cultural work with rusts have appeared. 
Prominent among them is a paper by KieBann," who reports the results of 
cultural experiments carried out from 1907 to 1911. Many of the results 
are new, while others confirm or supplement the work previously published by 
the author or other investigators. Unfortunately, the presentation is not 
sufficiently clear and concise to enable one to distinguish those which are new 
from those which confirm other work. In this respect the reports of ARTHUR, 
and likewise that of Fraser, might well serve as models. The main results 
given in the paper are summarized here. Uromyces Pisi (Pers.) DeBary, 
G. sanguineum L., while Puccinia Polygoni Alb. et Schwein. from Polygonum 
Convoloulus infected, Geranium molle L., but none of the others.
