FRAME HIVES. 93 
commended to be thoroughly greased before use, 
in order that thoy may easily be withdrawn—or a 
method of Mr. Taylor’s may be simplified thus: Take 
an elongated metal ring, like the link of a chain; 
under the middle of each projecting end of the crown- 
board make a slit which shall be capable of admitting 
this link, and through the latter there can be inserted a 
movable pin passed through a hole made from the end 
of the board; a screw driven into the side of the hive 
at the proper distance holds the other end of the link, 
and completes the fastening. The usual zine slides 
are fitted to the slits giving admittance to the super ; 
and not only should the regular close slides be pro- 
vided, but also a set pierced with ‘‘ queen-preventing”’ 
perforations (see page 66), which are to be substituted 
for the first, and retained in use as long as the super 
is applied.* As to the slits in the crown-board (for 
which see the figure of the pattern-gauge under “Bar 
Hives’), two of them are to be placed within three 
inches of the front of the box (inside measurement). 
They are pear-shaped, and, according to Mr. Taylor, 
they should be three inches long and an inch and a 
quarter wide, but the width may be increased half an 
inch or so if perforated slides are to be used. They 
are pointed at the inner end, and leave an intermediate 
space of two inches. The third hole may be an inch 
and a half from the back of the cover, and made an 
inch shorter than the other two; ‘this will be 
useful,” remarks the author, “in working glasses and 
* A very general practice now-a-days is to remove the crown-board 
entirely when the super is to be affixed, and to substitute an adapter 
consisting of a sheet of zinc perforated all over in this manner.
