to any tin shop and have a sheet-iron cylinder made, six feet long. Near the 

 back end, have a stovepipe hole made on each side. Put on pipe with elbow 

 running towards the front, and with elevation enough so that they may come 

 together in a T on the top of cylinder ; and coming to the outside on the end 

 just above door for wood. Here is an another elbow, and the pipe goes up the 

 end on the outside to a little above the ventilator. This is the best heater 

 known, and you can use any wood, even to pieces of rails six feet long ; it will 

 dry ten bushels of apples, or same of Black Cap raspberries, in a day. The 

 lower part of the end where the heater enters and pipe comes out, should be 

 of sheet iron. No grate is needed in cylinder. 



Some use eighteen or twenty inch cylinder, and add three feet more to 

 length and have space for three sets of trays. This gives longer return pipe, 

 too, and saves more heat in proportion. When completed this whole thing can 

 be tumbled on a wagon or stone boat and handled anywhere. Whole cost, with 

 wood slats or trays, about $20.

Jack Frost is the best friend we have. He kills off myriads and myriads 

 of germs which otherwise would produce epidemics of disease, and the alternate 

 freezing and thawing of spring and fall, have the same effect upon disease germs, 

 typhoid fever germs for instance, as it would have upon a field of corn after it had 

 sprouted. Germs that will stand either a great deal of cold or a great deal of 

 heat, are killed by a sudden cold snap, after they have been started into life by 

 a few days of warm weather, just in the same way that a field of corn a few inches 

 high would be cut down, whereas, the seed corn itself before the germination 

 would stand a great deal of cold without injury, and also a high degree of heat. 

 The alternations then, of heat and cold in the spring time and fall, are peculi- 

 arly beneficient in their influence upon life and health. If people were not so 

 careful to preserve typhoid fever germs in cesspools and wells this disease would 

 be entirely exterminated by the action of changes of the weather upon its germs. 

 Considering these things then, we ought not to find so much fault with the 

 weather, nor be so much discontented with its changes. — Dr. Kellogg in Fruit 

 Growers' Journal. 



Proper Tree Wash.— Whitewash on trees is unsightly and less effective 

 for repelling borers than common soft soap. Washed with the soap three or 

 four weeks after blossoming they will show the treatment speedily in greater 

 thrift and vigor. I have often used the following, which I think even better for 

 trunks and larger branches of fruit trees than soft soap : Heat to the boiling 

 point two gallons water and one gallon soft soap. When the soap is all dis" 

 solved add one-half gallon good, strong, crude carbolic acid and stir until all is 

 thoroughly and permanenty mixed. This, applied with cloth or brush, kills 

 bark lice, keeps off borers, and invigorates the trees. — ColmarHs Rural World.
