various plats with respect to the effects of the treatments on rusts and 
other fungi. After harvesting, the total yield of straw and grain, the 
yield of straw, and the yield of grain were each ascertained. From this 
data the following notes on the general effect of the treatment on 
each plat were prepared by Mr. Bartholomew : 
Plats 1 and 66.— Untreated. These were so near like all other untreated plats that 
their condition may be taken as a standard. Three fungi were noted upon the 
plants, viz, Puccinia rubigo-vera on nearly every leaf, Puccinia graminis on an occa¬ 
sional stalk, and Septovia gvaminuni on many of the leaves, hilt causing no serious 
damage. 
PI at 8 2 and 67, 4 and 69, 6 and 71. — Soil treatment with flowers of sulphur; yield of 
both straw aud wheat above the average, but the red rust was noticeable on every 
plant, not, however, in destructive quantities, as the wheat was full and plump. 
Plats 8 and 73, 10 and 75— Soil treatment with sulphur and lime; showed the usual 
amount of rust, with an average product of wheat and straw. 
Plats 12 and /7. Soil treatment with sulphate of iron; showed the rust in average 
quantities and yielded a medium amount of grain. 
Plats 14 and 79 .—Soil treatment with ferrous sulphate in water; did not show as 
good results in yield as 12 and 77. The usual amount of rust was present. 
Plats 16 and SI .—Soil treatment with Bordeaux mixture; showed normal amount of 
rust, and the yield fell considerably below the average. 
Plats 18 and 83 .—Soil treatment with sulphide of potassium solution; showed the 
usual mount of rust and yielded below the average. 
Plats 20 and 85.— Soil treatment with ammoniacal solution of copper carbonate; 
seemed to produce a bad effect on the germination of the seed, as the stand was thin, 
bacjly rusted, and the yield much below the average. 
Plats 22 and 87. Hot-water treatment of seed; showed normal amount of rust and 
decreased yield. 
Plats 24 and 89 .—Seed treated by immersing for twenty-four hours in 8:100 solu¬ 
tion of copper sulphate, then limed; showed usual amount of rust and a yield lower 
than the adjoining untreated plats. 
Plats 26 and 91— Seed treated by immersing for twenty-four hours in Bordeaux mix¬ 
ture; gave fairly good average results, but was rusted. 
Plats 28 and 93 .—Seed treated by immersing for twenty-four hours in a 5:100 
solution of potassium bichromate; badly rusted and yield lower thau the average. 
Plats 30 and 95— Seed treated by immersing for twenty-four hours in potassiurnsul- 
phide solution; produced fair results, though rusted as usual. 
Plats 32 and 97 .—Treated the same as the preceding, but with solution only half as 
6trong; yielded a very inferior crop, which was badly rusted. 
Plats 34 and 100 .—Seeds treated by immersing for twenty-four hours in 1:1000 solu¬ 
tion of corrosive sublimate; injured the vitality of the seed and gave a very light 
yield, with usual amount of rust. 
Plats 36 and 70;?.—Sprayed with Bordeaux mixture every ten days from October 
28 until June 24; yielded above the average and were not nearly so badly rusted 
as the preceding numbers or as the adjoining untreated plats. 
Plats 38 and 104 .—Sprayed every ten days with ammoniacal solution of copper car¬ 
bonate; also yielded in excess of the average and were very slightly rusted. 
Plats 40 and 106— Sprayed every ten days with sulphide of potassium solution. 2 
ounces to 3 gallons of water; did not show as good results, yet produced better yields 
than the adjoining untreated plats, being more free from rust but not so free as the 
two preceding groups. 
Plats 42 and 108 .—Sprayed every twenty days with Bordeaux mixture; yielded 
results very similar to plats 36 and 102, but showed more rust.
