Arsenate of Lead 
Arsenate of Lead 6 pounds 
Water 100 gallons 
It is better to purchase arsenate of lead than 
to attempt to make it. In mixing, preparatory 
to spraying, the amount of arsenate of lead 
for each spray tank full should be worked into 
a very thin paste having the appearance of 
milk of lime. It should never be thrown as a 
mass into the spray tank. This is a standard 
spray for codling moth and other eating in- 
sects. 
Kerosene Emulsion 
Kerosene 2 gallons 
Hard Soap (whale-oil soap) % pound 
Water 1 gallon 
Dissolve soap in water by boiling; add hot 
suds to the kerosene. Do not do this near a 
fire. Agitate the mixture with a spray pump 
so as to emulsify the oil. After five minutes 
the mixture becomes creamy. To use, dilute 
the above stock solution at the rate of one 
gallon to ten gallons of water. This is a stand- 
ard remedy for destroying green aphis, woolly 
aphis, mealy bugs and other plant lice. It 
may be used instead of tobacco solutions it 
desired. 
Corrosive Sublimate 
(Bichloride of Mercury) 
This is the standard disinfectant when work- 
ing with PEAR BLIGHT. No other disinfect- 
ant should be used to wash the cut surfaces or 
to disinfect the pruning tools. 
Corrosive Sublimate 1 part 
Water 1000 parts 
*1012 Spraying Calendar. Medford, Oregon. 
Corrosive sublimate may be purchased in tab- 
let form at drug stores and directions for mak- 
ing solutions will be found on the container. 
Never put corrosive sublimate into a metallic 
container; always use a glass bottle. Be sure 
to label the bottle “Poison" in large, plain 
letters. It is the deadliest of poisons. 
Whitewashes* 
1. Government Whitewash. 
Lime (unslaked) 40 pounds 
Salt 15 pounds 
Rice Flour (or ground rice) 3 pounds 
Spanish Whiting % pound 
Glue 1 pound 
Water 5 gallons 
Slake the lime in warm water and cover so 
as to keep in the steam; strain through a fine 
seive or strainer; add the salt, well dissolved 
in warm water. Then add the rice boiled hot; 
the Spanish Whiting; and finally the glue, 
which has been previously dissolved over a slow 
fire. Lastly add the five gallons of hot water. 
Stir well and let stand for a few days. Apply 
hot with a brush. One pint of the mixture will 
cover a square yard. Coloring matter may be 
put in, such as Spanish brown, yellow ochre, 
etc. 
How to Spray 
Drench every part of the tree. Spray thor- 
oughly. The most difficult places to reach 
should receive your most careful attention. 
Reach every crack, calyx cup, behind buds and 
in bud scales. Do not economize on spray ma- 
terial and sacrifice efficiency. Use a high pres- 
sure pump. 200 pounds pressure should be 
maintained. Spraying out of season is value- 
less. Determine what you must spray for. Use 
the right kind of material. 
My Dear Mr. Harman; 
In response to yours, just at 
hand, I am frank to say. my 
only regret since signing 
contracts with you, about 
seven years ago, has been 
and is that I was not with 
you throughout the many 
years I have been engaged in 
the Nursery business. Your 
quality products, courteous 
treatment of patrons and 
myself, and being so squarely 
back of all agreements, en- 
thuses me to keep everlast- 
ingly at it, and who knows 
but I will die with my boots 
on in your service. You 
know I am no Spring chick- 
en. Very sincerely, 
ALFRED H. DIPROSE.
