18 THE SAN JOSE OR CHINESE SCALE. 
that they were aware that they were distributing- diseased stock, since 
to deny- this presupposes that the stock received no examination. If 
the scale was noticed it was doubtless supposed to be one of the com- 
mon eastern species, which, while bad enough, are of little importance 
compared with the San Jose scale. 
The two nurseries responsible for the original eastern introduction 
of the scale became infested in the same way. Either in 1886 or 1887, 
in the endeavor to secure a thoroly curculio-proof plum, both of these 
nurseries introduced from California an improved Japanese variety, 
the Kelse} T , obtained from the San Jose district. We have the state- 
ment from the proprietors of one of the nurseries that the plum trees 
in question were secured in the spring of 1887 from San Jose, Cal., 
and were shipped thru the agency of a Missouri nursery company, which 
acted in this instance apparent^ as a mere transmitting agent. The 
trees were unquestionabl} 7 thoroly infested when received, did not 
thrive, and in both cases most of them were ultimately taken out and 
destroyed. The stock, however, had been multiplied by nursery 
methods, and from the original stock, and that subsequently obtained, 
the scale spread more or less completely thruout both of the nurseries 
in question. Both of these firms, when the nature of the infestation 
was brought to their attention and the seriousness of the damage they 
were doing was made apparent to them, undertook measures to 
exterminate the scale. 
In addition to the two prominent nurseries mentioned, several smaller 
nurseries in the East were found to harbor this scale. Some of these 
had been recently infested, but in others the infestation was of long- 
standing. Three nurseries of the latter class were located on Long 
Island, and apparently received their original scales from New Jerse} T ; 
one in Florida, reported by Prof. P. H. Rolfs, and two in Georgia 
apparently received infested stock from eastern sources, and one or 
more each in Louisiana, Mississippi, and Alabama became infested 
with the scale thru pear stock coming from Lewiston, Idaho. In Mas- 
sachusetts there were infested nurseries at Cambridge and Bedford, 
the origin of the scale in these cases being obscure; and a nursery in 
Missouri was under suspicion as having been the agency thru which 
the original infested Japanese plums were transmitted to eastern 
nurseries. Two infested nurseries were known to exist in Maryland 
also.
