line of each is the same distance from the inner angle 
of the super case as its notch is from the lower edge 
of the same — that is, the distance ab=an’, 2in. will 
be found to be ample. The screw upon which the 
strap turns must be the same distance (2in., e.g.) from 
the back of the hive body, and just so much more 
from the top edge of the hive as the super case laps 
over it. To remove the roof, it only needs to be 
lifted — when open, as at A — and the screws slip from 
their notches, and leave all free. The plinthed hive 
will be treated as at C, the plinth having a part 
chiselled out on the inner side, to admit the strap. 
The extreme comfort and convenience of this ar- 
rangement can only be understood by those who use 
it, and it only needs to be known to be extensively 
adopted. There is nothing to place on the ground ; 
the hive is opened and closed instantly, without 
possibility of error, and fastened automatically withal ; 
no chain to offer any impediment to the hands ; and a 
table provided capable of carrying chaff-tray and every 
requisite. With the loose hinge, the part sc (Fig. 17) 
is not necessary, as the roof-piece may be made of 
any depth. If doubling-box or supers, or both, be 
upon the hive, it is only necessary to lift the roof- 
piece from its loose hinges, and then place it over 
the honeyed tower. 
The frames of this hive, unlike those used by the 
Author, are supplied with what are called metal ends, 
of which several forms are in use ; one, which may 
do duty for all the rest, is represented in Fig. 21. 
The object of these metal additions is to keep 
the frames at their proper relative distances, to preserve
