DUTCH INSPECTION SERVICE

DUTCH INSPECTION SERVICE 



The following conununication was received by Dr. L. 0. Howard, 

 at whose suggestion it is publi^•hcd.^ — Ed. 



Wageningen, Sept. 6th, 1911. 

 De.\r Sir: 



Since this summer not only my oldest chief assistant. Dr. Quanjer, but also my 

 second chief ass stant, Mr. van Poeteren, is appointed by our Government for act- 

 ing as substitute chief of the phytopatholog cal service in my absence; he can also 

 put his signature on the cert.ficates. It seems to me necessary to send you now 

 the signature of h'm. On the accompanying cards I have brought together the 

 signatures of both my chief assistants who have been appointed as my substitutes, 

 and of myself, and I should feel myself very much obliged to you if you would be 

 so kind as to send those cards to those entomologists, horticultural comm'ssloners, 

 inspectors, etc., in tha different States who are charged with the inspection of the 

 packages with shrubs, trees and plants wh ch are sent from the Netherlands to the 

 United States of America. When it is good to send you more of those cards I 

 shall do so. 



I take the liberty to invoke your help, tor I do not know the names of the dif- 

 ferent gentlemen to whom th?y ought to be sent. 



I hope that I do not intrude too much on your kindness, and beg you to accept 

 my most respectful thanks for what you will do for me and for our phytopatho- 

 logical service. It shall be a great favor for me when I can help you in return in 

 sometliing. 



With very kind regards, 



Yours truly, 



J. RiTZEMA Bos.

CORRECTION 



Read lines 4 and 3 from the bottom of page 385 and after the word "preced- 

 ing," as follows: "22 and 22a, Mac. pisi, 23, apterous female of same; 24 and 25, 

 Mac. ambrosioe; 25 and 26a, Mac. sanborni." Because of too great reduction in 

 the dimensions of Plate 16, all amplifications are three fourths as great as indicated 

 on the plate. C. P. Gillette.
