UREDINEOUS INFECTION EXPERIMENTS IN 1904. 2 
W. A. KELLERMAN. 
The results of inoculation experiments here recorded con¬ 
stitute the third report of work in consecutive seasons with var¬ 
ious species of Uredinese. It has proved advantageous as in the 
previous years to attempt inoculations long in advance of the 
normal season for some of the species used. Not only repeated 
inoculations are possible the same season, thus at once removing 
possible doubt which is likely to arise in case of some of the 
successful inoculations, but this pre-season* work insures non¬ 
contamination or avoidance of accidental infection, that might not 
be vouchsafed in case spores are in the air outside the greenhouse, 
the wide distribution of which in the proper season should of 
course always be suspected. 
If testimony relative to the proposition just suggested were 
needed, the case of the Maize Rust related in detail below could 
be cited. Here the work of inoculation was begun in the middle 
of the winter (Jan. 16) and the successful inoculation was the 
starting point for an extended series of inoculations on different 
agricultural varieties of Maize and some other plants. When 
later work by another Uredinist was published which threw a 
shadow of doubt on some of the results, it was possible — then 
late in the season — to repeat the precise experiment alluded to 
and certainty was thereby restored. The work in detail will now 
be given.
