\lo., upon order John l\ock, San .lose, Csila,, as stated in ])revioiis 

 'Ommunication. 



We have destroy eil nearly all our orchard trees, as well as nursery 

 threes, of Japan plnins which appear to be favorites of the scale. AVe 

 have also dug out many large trees of Bartlett, Idaho and other pears. 



Professor Smith, of iS'ew Jersey Station, visited our grounds yester- 

 day and probably has reported to you. Should there be any new develop- 

 ments, or anything of interest transpire in connection with our efforts to 

 exterminate the scale, will advise you. 



Respectfully,

The insect fornieil the subject of two impoi'tant papers at the Sixth 

 Annual Meeting of the Association of Economic Entomologists in 

 Brooklyn the following August. One of these was by Mr. Howard, 

 giving a full account of the work done by the Department of Agricul- 

 ture and its results, and the other by Prof. J. B. Smith, of the Agricul- 

 tural Experiment Station, of. New Jersey. As a result of the discussion 

 at that meeting, the occurrence of the insect was subsequently established 

 in paj-ts of Columbia county, ]S'. Y., lying on the East bank of the Hud- 

 son river, below Albany, and in several localities on Eoiig Island. 



Still later in the season, as shown by some further notes of the sub- 

 ject by Mr. Howard, which he has prepared for No. 4, Insect Life, not 

 yet out, but of Avhich he has favored me with proofs, other localities 

 for the insect were discovered, viz., Southern part of Georgia; Clermont 

 county, Ohio; Newcastle county, Delaware; City Point, Prince George's 

 county, \lrginia, and at Jiristol, Pennsylvania; while three other 

 localities were added to Maryland, one in Prince George's county, one in 

 Anne Arundel county, and one in AVashington county. 



There can be no question but that future investigation will show 

 that the insect is quite widely disseminated in many other localities 

 yet undiscovered, not only in orchards and nurseries, but also in isolated 

 grounds, and that this general statement will apply to ^Maryland as well 

 as to the other States in which it has obtained a foothold; and, while the 

 energetic efforts that have already been made to stamp it out will go far 

 toward doing so, we must accept the situation, and acknowledge that the 

 species has come to stay. AVhile, therefore, I consider that its entire ex- 

 termination from so many points of infection over so large an area is im- 

 practicable and not to be hoped for, yet there is no reason why its spread to 

 other localities may not be very materially, if not entirely idiecked. This, 

 however. c;in only be done by intelligent action, not only on the part of
