COLLATERAL SYSTEM. 127 
between the two hives, so as, when in its place, to stop 
it entirely across the centre. 
Another plan of working hives side by side is shown 
below, two boards being required. They are made on 
the double plan, as 
described on page 76; 
alike in size and 
thickness, with the 
entrance passages cut 
out from beneath. 
There must, however, 
be two entrances to 
the board intended for the second hive—one in front 
and the other at the side, with doorways not less than 
six inches wide. A wedge or two of wood will contract 
them as needed. When room is required, the first 
board with its hive must be moved so far sideways that 
the second can precisely occupy its place. At the 
same time it must be turned half round, so that its 
mouth and that on the side of the new hive meet and 
fit close together. The bees will pass into the other 
hive on going out; on returning it will be the same, 
for the alighting-board (which ought to be a fixture) 
will remain as usual. On removing a full hive, the 
other must be restored to its original position. 
“Nutt’s Collateral Hive’”—a wooden bee palace, 
with central pavilion, octagonal cover, and two wings— 
is still occasionally met with; but it has wholly ceased 
to be recommended, and indeed the entire collateral 
system had all but become a thing of the past, when 
quite recently an inclination to make further trial of it 
sprang up in the apiarian world. Messrs. Neighbour
