ous. Cultural work without such conjectures based on field ob¬ 
servations are largely a waste of time, rarely leading to any 
positive information. The time to make observations is early 
spring, when the rusts first begin to show, mostly in April 
and May. Simple record of proximity is not especially im¬ 
portant. The observations must show that the inference is well 
established, that the new growth of spores has come from germ¬ 
inating spores of another sort found near by. The ability to 
work out such an inference marks the logical and acute ob¬ 
server. 
I desire to thank Messrs. Kellerman, Bates, Davis and Bar¬ 
tholomew for providing teleutosporic material, and also Mr. 
Holway for numerous favors. I have already mentioned the 
kindness of Messrs. R. Douglas’ Sons in providing host plants; 
strong plants of Callirrhoe involucrata were sent by Mr. Barthol¬ 
omew. My particular thanks, moreover, are due to the Botanical 
Society of America for providing funds by which the work 
could be prosecuted, not only in the laboratory but in the field. 
The observations at Fair Oaks, Ind., by far the most important 
of those made in a single locality, were rendered possible by the 
society’s generosity.
