that some scaly trees have gone out from New Jersey with my certificate 

 attached. I do not believe that I saw all these trees; in fact, I know 

 that some were bought by the nurseryman who sent them out. But, on 

 the other hand, I would not feel particularly guilty if it were proved 

 that I had really been in some of the blocks from which the scaly trees 

 were taken. I have no objection to admitting to an assemblage of this 

 kind my belief that in a lot of 250,000 peach trees in full foliage a few 

 may escape my observation, even if they are scaly. 



When we come to the point where the nurseryman puts his certificate 

 on all the stock that he sends out irrespective of where it is grown, of 

 course the danger of scaly stock getting out under certificate becomes 

 the greater. One New York nurseryman sent his tags with printed 

 certificate to his correspondent in Pennsylvania, and this correspondent 

 filled directly all orders for the particular stock grown by him. All 

 parcels were tagged from the supply furnished and all bore printed 

 certificates, though the only stock actually examined was growing in 

 Wayne County, N. Y. 



This is perhaps wandering a little from my subject, but it is in some 

 measure necessary, because it is important to indicate the fact that 

 limiting the scale distribution, even in a State where it is known to 

 exist, is by no means an easy task, because the sources of infestation 

 are so numerous and may be in localities of which no suspicion has 

 been entertained. It may also serve as a hint to some of my good 

 friends who have said uncomplimentary things of New Jersey that 

 their work of locating the scale is not all done when all who have been 

 supplied from that State have been visited. 



Almost all, if not all, the nurserymen in what may be termed the 

 nursery district of central and northern New York have certificates, 

 yet there is no doubt that thousands of scaly trees have been sent out 

 by them and not a few into New Jersey, else I could not speak of the 

 matter so positively. These trees will not, as a rule, be particularly 

 examined when the question of the presence of scale arises, because 

 the locality is not under suspicion, and only when it becomes so bad 

 that the condition of the trees arrests the attention of the grower will 

 they be brought to the attention of the entomologist. It goes without 

 saying that in a region of small farms, where almost every one contains 

 some fruit trees, personal inspection of all of them is hardly feasible. 



It is therefore impossible for me to say with certainty that I know 

 all the infested points in our State, but I think that I know sufficient 

 to speak of the general distribution. In no State has so much litera- 

 ture relating to the scale been so generally distributed; in no State do 

 farmers' institutes reach so large a proportion of farmers; in no State 

 is it easier to reach every locality by rail within a few hours, and in no 

 State has there been a more systematic effort to learn, by correspond- 

 ence and personal visits, the exact location of infested orchards. There 

 have been published in the past maps showing the general distribution 

 of the scale in the United States, and these give, quite unintentionally,
