failed to blossom; hence that the experiment, quite 
as in the cross with the Chinese quince, came to 
no result of practical valuc. 
But here, again, it should be borne in mind 
that more extensive experiments in hybridizing 
these related species might give us a combination 
that would be slightly less antagonistic. 
It goes without saying that a fertile hybrid be- 
tween quince and apple or between quince and 
pear would be a fruit of altogether exceptional 
interest and of the most inviting possibilities. The 
experiment of hybridizing these common fruits 
may readily be made by the amateur, and there 
are few simple hybridizing experiments that are 
more attractive as to their possible results or more 
instructive from a scientific standpoint. 
TEsTs WITH JAPANESE QUINCES 
The two remaining Oriental quinces have al- 
ready been named as Cydonia Japonica and C. 
mauiei. It should be added that the latter is prob- 
ably to be considered as a sub-species. Japanese 
quinces do not bear very freely, and their fruit 
has a great variety of forms, and is of such ex- 
treme acidity as fully to justify Beecher’s cele- 
brated formula—which, indeed, is said to have 
been suggested by an unfortunate experience with 
the Japanese quince. 
There is great diversity of bloom among
