SUMMAEY OF DISTRIBUTION AND PRESENT CONDITION.

so general in most of the States where the San Jose scale has occurred 

 for a number of years that it is impracticable to indicate the different 

 points of infestation, and even in* the States worst infested many 

 orchards are free from the scale; but if an attempt was made to graph- 

 ically picture the distribution on a map, the points of infestation 

 would be so numerous as to give the appearance of absolutel}^ complete 

 infestation. The publications cited may be referred to, therefore, 

 for the more detailed and complete records. A mere statement of the 

 present general status of the San Jose scale in the several States in 

 which it occurs will now be given. This statement is based on replies 

 to a circular letter of inquiry sent to State entomologists and experi- 

 ment station officers in May of this year.

scale up to 1896. (Original.) 



It is interesting for comparison to reproduce the map (fig. 1) show- 

 ing the known distribution at the time of the publication of Bulletin 3 

 in 1 896, when the scale was reported in only 20 States and in compara- 

 tively few localities in each, with the single exception of New Jersey, 

 which had been most energetically inspected by Dr. John B. Smith 

 and found to be very generally infested. Bulletin 12 records the scale 

 occurring in 33 States and also in the District of Columbia and Canada, 

 and in very man}^ new localities in all of the States previously recorded 

 as harboring the scale. The number of actual records of the San 

 Jose scale now available are man}^ hundredfold what the}^ were at the 

 time of the publication of Bulletin 12 at the' begmning of the year 

 1898. 



There are still a few States in which the San Jose scale does not 

 now occur or has not been reported, namely, Colorado, Maine, Minne-
