PROCEEDINGS OF THIRD DAY. 



Thursday, April 30. 1908, 9 : 30 o'clock a. m. 

 PRESIDENT JEFFREY. We have a little business to transact this 

 morning. As you know, it is customary to have a committee on resolu- 

 tions, and that committee will be composed of active men willing to 

 work. Sometimes the President appoints that committee without any 

 authority, but I would like to have your authority this morning, if you 

 choose, to provide for the appointment of the committee on resolutions. 

 I would like a motion to that effect. 



MR. CUTTER. I move that a committee of three on resolutions be 

 appointed by the Chair, 

 ^lotion carried. 



PRESIDENT JEFFREY. I will appoint A. V. Stubenrauch, C. B. 

 Messepger. and H. C. Rowley. :\Ir. Geo. H. Cutter and Mr. C. C. 

 Chapman will advise with that committee. All resolutions will.be 

 referred to the committee, unless some member desires to bring a 

 resolution before the house. We will now hear from IMr. R. S. Woglum 

 on "Investigations of Hydrocyanic Acid Gas." I will say that Mr. 

 Woglum represents the Department of Agriculture. An appropriation 

 of $10,000 was made nearly two years ago for investigating the use of 

 remedies for orchard pests. Mr. Woglum Avas selected by the depart- 

 ment for this work. He has been at work nearly a year, and about 

 the first of January i\Ir. Maskew was taken awaj' from me by the 

 department — a very common thing, by the way — and given work jointly 

 with ]Mr. Woglum. the latter being in charge, and ]\Ir. Maskew his 

 local assistant. I secured the privilege from the Department of Agri- 

 culture to have these young men make some advance statements to you 

 in regard to what they may have discovered. I take pleasure in 

 introducing ~Slv. Woglum. 



INVESTIGATION OF THE USE OF HYDROCYANIC ACID GAS 

 IN FUMIGATING CITRUS TREES. 



By R. S. woglum. of the Department of Agriculture. Washington, D. C. 



In July. 1907. the speaker Avas detailed by the Assistant Chief of 

 the United States Bureau of Entomology to proceed to Southern Cali- 

 fornia for the purpose of commencing a scientific investigation of the 

 use of hydrocyanic acid gas in the destruction of injurious scale pests 

 of the citrus. Arriving in Los Angeles during the last days of that 

 month, consultation was held with the Hon. J. W. Jefl^rey, the president 

 of this meeting, who, it is well known, assisted materially in bringing 

 about this investigation, and whose interest in the subject was naturally 

 great.
