There were confident anticipations

of 2S, 1872, 900 bushels of wheat
rom 916,664 acres, IA, 76s, 600 bushels of
BATS from 305,644 acres, and 3l9s, 900 |
bushels of barley from 80, S2s acres for
he crop of 1892. These estimates were |
from barley and oats; but fields |
'lowed for wheat in the spring were
injured by frost, and the exposure of Il
arge portion of the crop in open stocks
md badly constructed stacks reduced
he aggregate of wheat available from
1anitoba and the northwestern terri
ories to 15,0OO 900 bushels; nor has the
eturn to the producer exceeded 80
