a tripod about two feet from the ground, the peaflour bunch being removed 
beyond the reach of the rain. Here the bees will shelter in inclement weather, 
and even when the sun is bright they will load themselves with peaflour 
pollen. This artificial food is stimulating, and the bees thrive well on it. 
TO FIND THE NUMBER OF GALLONS RAISED BY A PUMP. 
Frnsr find the diameter of the pump cylinder and then the length of stroke. 
Square the diameter of the cylinder, multiply this by the length of the 
stroke, and divide by 353. The result will be the number of gallons of water 
raised at each stroke of the piston-rod. 
Of course, the number of strokes per hour must be known, and also the 
question of resistance, owing to the height to which the water has to be lifted, 
must be considered in getting at the hourly work of the pump. 
EXAMPLE, 
Diameter of cylinder, 3 inches 
Length of stroke, 12 inches 
3xXx38=9 
9 x 12 = 108 
108 + 353 = °3005, or about + gallon per stroke. 
The amount of water raised by a single-action pump in twenty-four hours 
would then be equal to the quantity raised per stroke multiplied by the 
number of strokes per hour into the twenty-four hours, supposing the pump 
working night and day. 
EGG-TESTER. 
We illustrate an ege-tester which cannot be surpassed for determining the 
fertility of eggs after setting, and also for ascertaining whether the chick is 
alive in its different stages from two or three days up to the time of hatching. 
By throwing out all the infertile eggs and dead chicks, whether in incubators 
or under hens, a great saving of time is effected when the hatching season is at 
its height. By its use breeders can also determine in a few days whether the 
eggs they are sending out to customers are generally fertile or not, and in this 
way making a saving to themselves and their customers of time, patience, and 
money, ‘The tester is made by cutting a hole in the north side of a building 
or a large dry-goods box, and having a mirror outside in such a position as to 
reflect the sun’s rays direetly into the hole, and upon the eggs, held against it 
from the inside. The inside, of course, should be as dark as possible. Our 
illustration is so clear that further description is not necessary. This method 
of testing eggs has been used for a number of years, and has been found 
convenient and practical.— Weekly Times,
