EXPLANATION OF PLATES. 485 



PLATE HI. Fig. 10 shows the arrangement of the circular, 

 saw to cut the triangular comb-guides. 



The first piece cut is waste ; as fast as a guide is sawed, the 

 piece from which it is cut, must be turned over, end for end. 



PLATES III, V and VI. Figs. 11, 12, 17 and 19 show the 

 construction and position of the Entrance-Regulators. 



Fig. 11, is a rigiit angled triangle |-ths thick by 4 by 5| by 7. 

 Fig. 12, is a right angled triangle ^ inch thick, by 7 by 

 4 by 5f . In the bottom of ihe first piece, grooves are cut 

 ^ deep by ^ an inch wide, as traps for the larvse of the bee^ 

 moth, (p. 269.) On the face of the second piece, strips -^ 

 of an inch thick are placed, two of which are ^ =11 inch wide 

 and are placed as shown in Fig. 12, parallel with the 4 inch 

 side, and so as to leave a space of ]^ inches between thenn 

 and the second and third piece, which last piece is a right- 

 angled triangle. In the spaces between the strips just men- 

 tioned, cut Fig. 12 to a bevel of 45°- Now fasten very se- 

 curely the two blocks, so that there will be no chance for 

 any alteration of ihe ^^ inch passage, by warping or swell- 

 ing. To test the accuracy of the -f^ inch strips, put four of 

 them together and if they measure just f ihs, they will answer 

 for confining the queen, (p. 201.) If there is no desire to 

 prevent swarming,* then Fig. 11 will answer, without the ad- 

 dition of Fig. 12. Two of these doubled blocks, made right 

 and left are used for a hive. When Figs. 11 and 12 are 

 fastened together, the corner made by the meeting of the 7 

 inch and 5f inch sides, should be very slightly clipped, so 

 that the 7 inch side will measure a scant ^ of an inch less than 

 7 inches. To confine the queen, turn over the blocks and 

 place them with the 7 inch sides against the front of the hive, 

 keeping them pushed up close to each other. To confine the 

 drones (p. 455,) or to shut them out, (p. 202,) leaving the 

 queen room to pass, put the blocks in the same position, only 

 pushing them about ^ of an inch apart. By varying the 

 position of these blocks on the alighting-board, (see Fig. 17, 



*The Author has not experimented sufficiently on this plan of pre- 

 venting swarming, to be aljle fully to endorse it ; (see p. 203.)
