BULLETIN 822, IT. S, DEPARTMENT OE AGRICULTURE, 
of 450,000 bushels or more, though in several other States, as, for 
example, Colorado, Utah, Delaware, Texas, and Illinois, there are 
places where the pear orchards are of more than local importance. 
OUTSTANDING FEATURES OF THE PEAR INDUSTRY. 
The census figures for 1890, 1900, and 1910 show (in round num- 
bers) 5,100,000, 17,700,000, and 24,000,000 pear trees of all ages in the 
country, thus indicating a rather constant and considerable increase 
from year to year. 
Of the trees re- 
corded in 1910, about 
8,800,000 were re- 
ported as not of 
bearing age. No 
similar segregation 
of trees of bearing 
and nonbearing age 
was made in the 
census reports of 
1890 and 1900. 
FAIRLY CONSTANT TO- 
TAL PRODUCTION. 
The estimates of 
production shown in 
Table I and in fig- 
ure 2 indicate a 
fairly constant yield 
for the country since 
1910. While the

Fig. 3. — Diagram showing the estimated annual average poses has been CX- 
farm production of pears in the principal pear-producing fp-n^prl iri rpsCPTlt 
States for the 5-year period from 1912 to 1916, inclusive. ^"uou 
The average yearly production for the entire United States years in Some locali- 
for this period was 11,425.000 Imshels. ^ ^ ^ industry 
has been newly established in a few regions, it is also true that many 
orchards planted for commercial purposes have been destroyed dur- 
ing the last two decades. The conclusion, therefore, is that the in- 
creases in the number of trees shown by succeeding census reports 
are made up principally of trees that represent home interests rather 
than commercial •activities. 
MENACE OF FIRE-BLIGHT. 
To those familiar with the situation, the outstanding feature in 
pear growing is the menace of fire-blight.
