that a few farmers are changing their practice 
accordingly. This practical crossing is accom- 
plished hy planting in one row one variety and 
in the next another, and removing the tassels 
of the one as soon as they appear. Of course 
the ears of the plants lacking tassels will be 
fertilized by the other row where pollen exists, 
thus producing a cross from which seed may 
be selected. 
Not much effect may be seen as the result of 
planting crossed seed the first year, while the 
second it may be very marked. 
Interesting data concerning several crossing 
experiments is given by McCluer in the bulle- 
tins previously referred to from which the fol- 
lowing notes are gleaned. Figs. 60, 61 and 62, 
loaned by the Illinois station, show the effects 
of some cross fertilizing done there: 
“Of 142 plats planted with sweet corn, pop corn, and these 
crosses, it is safe to say there was as much uniformity in any 
one of the crossed plats as in any, and very much more than 
was found in most of the plats planted with pure varieties. 
“Corn grown from the crosses the second year has con- 
tinued to be comparatively uniform in type where the parent 
varieties were similar; but where the parent varieties were 
widely different, as in the crosses between sweet and dent, 
the progeny has tended strongly to run back to the parent 
forms, while at the same time taking on other forms differ- 
ent from either. ὃ 
“From the work so far done there seems to be no way of 
telling beforehand what varieties will, when crossed, pro- 
duce corn of an increased size, and what will not. 
“In the production of new varieties by crossing it will
