one in this locality. My assistant visited this section three times during 

 the past summer and autumn and each time found new localities where 

 the scale existed. In his report he says: "I visited a good many places 

 in the suburbs of the city and found scale at every one. It has become 

 so thoroughly established that it can not be checked except by a whole- 

 sale cutting and burning and by a thorough use of the spray pump in the 

 hands of a competent man. The infested trees mostly belong to people 

 who have small places, and as a rule do not like to lose them or to go to 

 the expense of spraying. It requires an official notice for each one, and 

 then a second trip later in order to be sure that the work has been done. 

 Almost all raise some objections to doing the work as required by law." 



Here is a marked contrast to the conditions found in Perry County, 

 where the fruit growers are awake to their own interests. 



At this point I wish to repeat what I said in my report one year ago, 

 that "in view of the fact that a large part of this section of the State is 

 well adapted to' fruit growing, and that numerous commercial orchards 

 are already being developed there, it is exceedingly important that object 

 lessons be given these people in the matter of exterminating or holding 

 in check the various insect and fungous pests of the orchard. This can 

 only be done by placin.g a competent man in the field with the necessary 

 spraying outfit where the San Jose scale now exists, and keeping him 

 there until the entire infested district has been covered. This I have not 

 been able to do on account of our meager appropriation, which is barely 

 enough to complete the inspection of the nurseries of the State as re- 

 quired by law." 



A little more than a year ago my assistant found the San Jose scale 

 on some fruit trees in the town of Linton, Greene County. This county 

 probably contains more nurseries than any other county in the State, 

 and so efforts have been made to clean up this scale-infested spot, but 

 most of these town lots are either owned or rented by miners who are 

 not accustomed to the use of spray mixtures or do not have the time to 

 devote to the work of spraying. Howevex', it was found, during the past 

 summer, that many of the infested trees had been cut down and burned 

 and the instructions followed, except in a few cases; so that only a few 

 live insects were found; but the fact that this insect multiplies at such 

 an exceedingly rapid rate* makes it an enemy to be dreaded by every 

 fruit grower and especially by the nurserymen whose premises are located 

 within a few miles of the infested spot. 



During the year I found eight new outbreaks of the scale. One of 

 these is in Montgomery County, near Ladoga, one in Wayne County, near 

 the Fayette County line, two in Jefferson County, already mentioned, and 

 four in Switzerland County. With the exception of Switzerland County, 

 these are all mild cases, being confined to single orchards, and can be 

 easily controlled if looked after carefully. 



''■'It has been demonstrated that a single female scale may become the progenitor of 

 more than three billions of individuals^in'a'single seagon.
