A PRELIMINARY REPORT ON THE 
pockets (produced by Taphrinci pruni) on native wild varie¬ 
ties. The bacterial disease, variously known as “ pear 
blight,” “ apple tree blight,” “ twig blight,” is prevalent, and 
in some sections has done great damage. Our insect enemies 
are numerous, and their attacks must be met by persistent 
warfare on the part of the fruit grower. The best line of 
attack against most of these pests is well understood, but 
remedies for some of the new T er ones are yet matters for 
experiment. 
In the Western District, diseases and insect troubles 
are at present unknown, but it cau hardly be hoped that 
the immunity now enjoyed will continue. Growers in* 
that district should prepare themselves to profit by the 
experience gained elsewhere and meet the first attacks 
with determined efforts at extermination. 
The rapid advancement of the fruit industry has al¬ 
ready called forth the prediction of over-production. 
There is nothing, however, to cause apprehension of this. 
As yet, the home market is not nearly supplied, as is 
shown by the fact that in 1890 very nearly all of the 654 
car-loads of green fruits shipped into Denver by freight 
came from other States. We have a rapidly increasing 
population, which will insure increased home demand for 
fruit. When production exceeds the home demand, there 
is no reason wdiy the Colorado product cannot enter the 
larger markets of the country in competition with other 
fruit producing regions. California growers market with 
profit in the Eastern cities; our growers are enough nearer 
these great markets to make competition easy. The markets 
of the South also offer an excellent and easily accessible 
outlet for much of the fruit that can be raised here ; but I 
apprehend that with all our increase of production, it will 
yet be some years before markets need be sought abroad. 
There is a possible danger in sight—it is the danger of 
overstocking the market with inferior fruit. As fruit be-
