1900] Robinson,—A blue-fruited huckleberry 81 
tion under lenses of highest magnifying power. To this end various 
methods of manipulation have been suggested. For some species it is 
desirable to mount the sporangium on the slide dry, in natural condi- 
tion. This is essential in studying the Stemonitis species and the 
Cribrarias. Blown-out specimens are to be selected. In ordinary 
cases, however, we must resort to other methods, methods which will 
bring to all parts their natural fullness and will also render them less 
opaque. For these purposes, for temporary mounting, a weak solution 
of potassic hydrate will be found serviceable, to be followed by glycer- 
ine, if the specimen is to be kept any length of time. 
But of the various matters of microscopic technique it is perhaps 
less needful here to speak. It is rather sought here to win for a 
hitherto little-noticed, but certainly remarkable group of living things 
a wider place in the attention and regard of students. Of course, for 
the proper appreciation of these things we must be children of nature, 
lovers of the natural world and sympathetic with all that goes on there. 
The consolations, the delights of nature are not for those who label 
things, who spend time in a vain attempt to harmonize the rules of 
nomenclature ; her rewards are for those who love to watch the con- 
sistent harmony of her deathless cycles, and who in the secrets of her 
humblest forms can read the stately march of her sublime ongoings.

A BLUE-FRUITED HUCKLEBERRY. 
B. L. ROBINSON. 
WHILE collecting some plants on the eastern shores of Thorndike 
Pond at Jaffrey, N. H., in the late summer of 1896, I noticed two 
varieties of fruit on the huckleberry bushes (Gaylussacia resinosa). 
The berries on some bushes were, according to the laws laid down for
