All the stocks were sprayed on the same dates; in 1891 on May 21, 
June 3 and 24, July 9 and 24, and August 8 and 28. One-half the 
stocks were treated seven times, on the dates just indicated, and one- 
lialf only three times, on the first three dates named. In 1892 the dates 
of treatment were May 26-27, June 15-16, June 23, July 6-7 and 21, 
and August 5. One-half were sprayed five times, on the first five dates 
mentioned, the other half six times as just indicated. The only fungi¬ 
cides used were Bordeaux mixture and ammoniacal solution. In 1891 
both preparations were of essentially standard strength, but in 1892 
the Bordeaux mixture was reduced to the 60-gallon formula, as ex¬ 
plained on a subsequent page (p. 262). 
FRENCH PEAR STOCKS. 
1891. —Four rows (1,922 stocks), of which 1,462 were treated and 460 
left untreated. One-lialf the treated stocks were sprayed Avith ammoni¬ 
acal solution, the other half with Bordeaux, at the dates above indicated. 
Although the disease was not so abundant in 1891 as in 1892, the con¬ 
trast between treated and untreated was striking. Seven treatments 
with Bordeaux proved efficacious, while neither three treatments with 
Bordeaux nor seven with ammoniacal solution showed as good results, 
and three treatments Avith ammoniacal solution were Avithout apparent 
effect. On October 9 a count of those stocks forced by the premature 
fall of the foliage to put forth new leaves gave the folloAving figures:

1892 .—The same rows of stocks as Avere employed in 1891 were treated 
in 1892, but one-half of them had been budded the fall previous, as sub¬ 
sequently described on pp. 258, 261. The other half was purposely left 
unbudded to furnish a means of testing the fungicides. The treatments 
were made on dates given above, using the formulse mentioned on p. 
262. During the course of the season little difference between treated 
and untreated budded stocks was noticeable, as none but the Flemish 
Beauty were subject to the disease. At the close of the season, how- 
eA^er, the foliage on treated Flemish Beauty was much superior to that 
on untreated. Bordeaux proved superior to ammoniacal solution and 
entirely efficacious. 
The greatest contrast in the experiment Avas between the treated and 
untreated stocks Avhich had not been budded. The susceptibility of 
these unbudded seedlings afforded an excellent opportunity to test the
