SUMMARY OF DISTRIBUTION AND PRESENT CONDITION. 29 
OKLAHOMA. 
The first records of the San Jose scale in Oklahoma were received 
in 190Jr, on Japan plum from Mulhall. We have since received it, in 
1905, on peach from Stillwater and El Reno. Mr. J. F. Nicholson, 
entomologist of the agricultural experiment station, reports that the 
scale has been found to a limited extent in five places in the Territory, 
namely, Mulhall. Shawnee, El Reno, Wellston, and Chandler. All of 
these cases are trees in city gardens. 
OREGON. 
Mr. A. B. Cordley, referring to presentconditions in Oregon, states 
that to enumerate the localities where the San Jose scale is found would 
be practically to include all places where fruit is grown. He says that 
it occurs in a very large proportion of the orchards in western Oregon, 
from Ashland to Portland, particularly those along the lines of rail- 
roads or in the vicinity of towns, there being scattered orchards back 
toward the foothills which the San Jose scale has not }^et reached. It 
occurs also between Portland and Astoria, along the Columbia River; 
is present in the Hood River Valley; in the Walla Walla Valley in the 
vicinity of Milton and Free water, and in the Grande Ronde Valley in 
the vicinity of Vale and Ontario. There are, however, large areas of 
central and southern Oregon, remote from the railroads, where little 
fruit is grown, that the scale has not yet reached. It is noted, how- 
ever, that the scale does no great injury except in small farm orchards 
or those that are neglected, and that in all the large orchards the lime, 
sulfur, and salt mixture as a winter spray is in general use. 
PENNSYLVANIA. 
The San Jose scale became earl3 r established in Pennsylvania from 
New Jerse}^ nurseries, but the subject of San Jose scale control was not 
taken up as early in this State as in neighboring States, so that the 
conditions at the outset were not well known. Both Prof. H. A. Sur- 
face, economic zoologist of the State, and Mr. George C. Butz, the 
horticulturist of the agricultural experiment station, agree in the state- 
ment that the San Jose scale is now so widespread in Pennsylvania 
that there is scarcely a county that has not points of infestation. It 
occurs in practically all the important fruit regions of the State, and 
in many private and public grounds, especially in the portion of Penn- 
sylvania lying east of the Allegheny Mountains. Mr. Butz reports 
that probably 20 per cent of the orchards are more or less infested. 
Professor Surface has, with the assistance of 30 inspectors, taken up 
active warfare against the scale, inspecting orchards and nurseries and 
trees in parks and giving demonstrations in methods of suppressing 
it. He states that he has not found the scale in the three northeastern
