PERFECTION IN 



THE weather bureau of the United 

 States Department of Agriculture 

 has been able to discover the weapon 

 used by that old enemy of mankind, 

 Jack Frost, and in a recent published 

 report it tells the farmer and fruit 

 grower just what Jack's invisible wea- 

 pon is, and how, under ordinary condi- 

 tions, the sprite's own artillery can be 

 used against him. 



Frost, of coures, occurs whenever the 

 mercury drops to 32 degrees Fahren- 

 heit or lower. If much moisture is pres- 

 ent in the atmosphere this drop in tem- 

 perature is manifested by the white

 Poultry Book 



With Plans for an Ideal Brooder 



My brooder plans tell how to make a 

 brooder for 100 to 500 chicks. Use one- 

 burner oil cook stove for heater. I threw 

 out my coal and distillate stoves when I 

 invented this system. No thermometer or 

 thermostat needed. No over-heating, chill- 

 ing, worry or grief. No burnt air in the 

 brooder room or hover. Don't need to 

 teach chicks to roost. A child can operate 

 it. Very simple. Turn any old shed into 

 a brooder house. Directions for new house. 



Feeding directions for chicks tells not 

 only just what to feed, but exactly how 

 much — right to the ounce — no guess. No 

 gapes, toe-picking, leg- weakness, diarrhea, 

 etc., in our chicks. 



My book also contains my feed formulas 

 and methods that save me 25c to 50c a hen 

 a year, and produced fourteen 300-egg hens 

 out of the 450 pullets. How I fed a test 

 pen of 90 pullets one grain feed a day and 

 got four 300-egg hens. How I selected the 

 pullets from the general flock to be trap- 

 nested that made so many high producers. 



Other items are : Self-feeding hoppers 

 that are absolutely wasteproof. Artificial 

 lighting. Self-cleaning chicken crates. Self- 

 cleaning nests. Sanitary dropping board 

 with miteless roosts. No. 1 Mite Paint at 

 10c to 25c a gallon. Wet mash mixer for 

 500 to 1000 hens for $1, etc.

crystals of frozen moisture upon leaf or 

 grass stem, and there is what is known 

 as "white frost." If the temperature 

 drops to the required degree and does 

 not reach the point when water from 

 the air is condensed, there will be few 

 crystals deposited, and the result is a 

 "black frost." A "freeze" is the term 

 applied to a condition of cold more 

 permanent than frost, and such a con- 

 dition may occur when there are high 

 winds. True "frosts" occur only when 

 the surface air is relatively calm. 



Temperature, like water, seeks a lev- 

 el. During the day the earth receives 

 more heat than it can throw off, but at 

 night, this supply of heat is stopped. 

 During the day the heat thrown off 

 by the earth warms the thin blanket of 

 air next the ground. This blanket, as 

 it warms, loses its density and ascends. 

 Cooling as it rises, presently it en- 

 counters air of its own temperature, 

 and there it stops. Meanwhile its place 

 has been taken by other colder air, 

 which is in turn warmed by contact 

 with the ground. This exchange goes 

 on until, at sundown, all the air of a 

 wide layer above the earth has been 

 warmed, and the highest temperature 

 is felt nearest the earth.
