OBSERVATORY HIVES. 
The simplest of these is in form lke an ordinary 
frame hive with its sides composed of glass as in the 
figure annexed, or more usually now, with the crown 
of glass also, and the open- 
ings into the super cut 
through this. The hive 
should be placed in a house 
and in winter carefully 
covered; an outer case or 
box going over the whole 
—that is to say, if the risk of keeping the bees in 
such a hive during winter is encountered at all. 
Another form is that of the ‘Circular Observa- 
tory Hive,” the general features of which are here 
shown. This hive is adapted 
for placing within-doors, a 
glazed tunnel connecting the 
entrance with an opening 
cut through the window-sash. 
A glass dome or cylinder 
forms the stock-hive, within 
which are a number of wooden 
bars supported by a pedestal 
and designed for the same 
purpose as the bars in other 
hives ; an opening admits to 
a bell-glass super, and, over 
the whole, a straw skep fits as a cover. Messrs.
