GLEANINGS IN BEE CULTURE. 



Feb. 15 



jegfulated, he has something- like a busi- 

 ness-like arrangement. 



The air comes in at the center of the cel- 

 lar floor. It is connected with a sub-earth 

 ventilator of three thirty-foot lengths of 

 eight-inch glazed tile joined with cement, 

 making it water-tight. It is laid 8 feet be- 

 low the ground, and connects with an up- 

 right pipe 25 feet high, and on top of it is a 

 cowl always facing the breeze. The air 

 passes through the sub-earth ducts; and 

 they, being water-tight, can not get any 

 moisture from them — a defect that many 

 sub-earth ducts have. But the temperature 

 is raised by passing through the warm 

 earth, as the temperature of the air enter- 

 ing it rises and becomes more capable of 

 taking up moisture. 



In the plan you will notice two partitions 

 running" crosswise of the cellar; and two, 

 again, join these. In this center compart- 

 ment stands a self-feeding coal-stove, and 

 it stands right over (but two feet from) the 

 floor where the cold air comes in. This 

 stove regulates the temperature, and, after 



being warmed to the required temperature, 

 it passes into the bee-cellars through wood- 

 en pipes at the top, which discharge in the 

 far upper and outer corners of the cellars. 

 The stovepipe enters a double chimney, one 

 part for the stove, the other for a foul-air 

 vent. At the opposite side (but nearest to 

 the two wooden partitions) is a foul-air 

 pipe which, by means of vents and stops, 

 can be made to draw the air from either 

 the top or bottom of the cellar. These 

 pipes draw oft" the foul air, and at the top 

 of the chimney is another cowl, just the op- 

 posite of the previous one, which has its 

 back always to the wind, and thus becomes 

 a suction cowl. 



In this way temperature and current of 

 air can be controlled. The cellar is new, 

 and 70 of these colonies never had a flight 

 after being- two days closed up on the cars, 

 yet all appear to be wintering- well — cer- 

 tainly a ver3' severe strain on its qualities 

 for wintering. I find that, when cold walls 

 are exposed to the atmosphere, the moisture 

 condenses there; but here not a particle of
