NUTT'S COLLATERAL HIVE. 57 



manager should carefully take off the empty end box he 

 intends to open to them, and thoroughly cleanse it, and 

 then smear or dress the inside of it with a little liquid 

 honey. Thus prepared, he must return the box to its 

 proper situation, and then withdraw the sliding tin that 

 hitherto has cut it off from the middle box ; by so doing, 

 the store-room is again enlarged. The bees will com- 

 mence operations in this new apartment. This simple 

 operation, performed at the proper time, generally pre- 

 vents swarming ; by it the queen gains a vast addition to 

 her dominions, and, consequently, increasing space for the 

 multiplying population of her domicile. Provided the 

 weather continue fine, and the thermometer has risen to 

 ninety-five degrees, as marked on the scale, the remain- 

 ing tin may be also withdrawn, thereby giving the bees 

 admittance to another box. There is now no lack of 

 store-rooms or of employment for our indefatigable 

 labourers. The cylinder thermometer is required to be 

 occasionally dropped into the ventilating tube of the side 

 boxes to ascertain their temperature; for, if exceeding 

 or approaching that of the middle box, it must be 

 reduced by ventilating : this is done by raising the zinc 

 tops, to allow the air to pass through the perforations. 

 The grand object of this system is to keep the end boxes 

 and the bell-glass cooler than the pavilion or middle 

 box, so as to induce the queen to propagate her species 

 there and there only, and not in the depriving part of 

 the hive ; by this means the side and upper combs are
