only treatment the soil received was a dressing in November and December of 1891, of 
33 wagon loads of well-rotted barnyard manure from the station manure platform, 
evenly distributed between the rows. 
The stocks were furnished by various nursery firms as stated in a previous article,* 
and the different lots were of apparently equal vigor—first grade with the exception 
of American pear stocks, which owing to tlie lateness of the season were third grade. 
In the planting which was done between the dates oL April 27 and May 3, care was 
taken that each stock was firmly pressed into the soil. Stocks of the same kind from 
different nursery firms were thoroughly mixed together. In all respects the normal 
nursery methods were followed out ;>s nearly as possible. The budding was done on 
the dates above recorded by two experienced budders employed by the Station. The 
scions for cherry, pear, and apple buds were cut from trees growing in the nursery 
rowst of Selover and Atwood. Plum scions were furnished by Maxwell & Bros., 
from their bearing orchard. 
Treatment with fungicides. — Only the two well-known fungicides, ammoniacal so¬ 
lution of copper carbonate and Bordeaux mixture were used. The formulae used in 
1891 were those in common use throughout America. The Bordeaux mixture was 
diluted in the treatments for 1892 and prepared after the manner first proposed by 
Dr. G. Patrigeon.f 
The formulae are given below: 
Ammoniacal solution of copper carbonate, formula used in 1891. 
Five ounces of cupric basic carbonate (copper carbonate) dissolved in ammonia 
(3 to 4 pints of 26 °) and added to 50 gallons of water. Care was taken that all the 
carbonate was dissolved in the ammonia, enough being added for the solution. 
• 
Ammoniacal solution of copper carbonate, formula used in 1892. 
Identical with the above in strength. The carbonate was wetted with one pint of 
water, previous to adding the ammonia, to facilitate the solution. 
Bordeaux mixture, formula used in 1891. 
Six pounds of cupric sulphate (copper sulphate or bluestone) dissolved in 12 gal¬ 
lons of water. I our pounds of stone lime slaked in a small quantity of water and 
made up to 3 or 4 gallons ol thin milk. The lime was added slowly to the .cupric 
sulphate and the whole made up to 22 gallons. 
Bordeaux mixture, formula used in 1S92. 
Two pounds cupric sulphate dissolved in 15 gallons of water. Two pounds Rhode 
Island stone lime slaked in small quantity of water and made up to 5 gallons. 
The lime was added slowly to the cupric sulphate, testing the mixture frequently 
during the addition with a few drops of a concentrated solution of potassium fer- 
rocyanide (yellow prussiate of potash) and ceasing the addition of the lime when 
no red color was given to the drops of the ferrocyanide. For convenience this may 
be called a 60-gallon formula, as it requires that amount of water to contain as 
much copper sulphate as the standard strength, viz, 6 pounds.

t A practice much in vogue among nurserymen, but certainly not founded upon a 
knowledge of the laws governing bud variation. The selection of buds from indi 
vidual bearing trees of known vigor and productiveness is insisted upon by the best 
cultivators.
