of 450,000 bushels or morey^ thougk in several ©tlier 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', aond 19'M show (in romnxi num- 

 bers) 5,100,000, 17,700,000, and 24;,00O,000 peajr trees of all ages in the 

 country, thus indicating a rather constant and considerable in.ci-ease 



from year to year. 

 Of the trees re- 

 corded in lOiOy 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..

The estimates of 

 production shown in 

 Table I and in fig- 

 ure 2 indicate a 

 fairlj^ constant yield 

 for tlie country since 

 1910. While the

The average yearly production for the entire United States vears in SOine locali-

has been newly established in a few regions, it is also true tha.t 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, tlie outstanding feature in 

 pear growing is the menace of fire-blight. This disease, doubtless
