Murrill: The Fruit-Disease Survey 51 



diseases. The party spent August 4 in Berkeley County, West 

 Virginia, noting the effects of cedar eradication, visiting orchards 

 where dusting and spraying experiments were in progress, and 

 inspecting demonstrations of collar-blight and other diseases. 

 Visits were also made to the experimental packing plant at In- 

 wood, and to the West Virginia pathological weather instrument 

 station near Martinsburg. August 5 was spent in the vicinity of 

 Hagerstown, Maryland, and was largely devoted to peach diseases 

 and their control by dusting and spraying, some attention also 

 being given to truck-crop diseases. On August 6, the party 

 visited the Field Laboratory of the Pennsylvania Agricultural 

 Experiment Station at Arendtsville, Pennsylvania, and inspected 

 experiments in progress in that region under direction of the 

 laboratory staff on the control of apple diseases and insects. The 

 conference adjourned at Gettysburg, but on August 7 a portion 

 of the party continued by automobile to Philadelphia, visiting the 

 rich agricultural districts of Lancaster County and inspecting the 

 tobacco experiments in progress there. 



Wednesday evening, we were guests of the Chamber of Com- 

 merce of Hagerstown, Maryland. After the usual exchange of 

 courtesies, the representatives of foreign countries were called 

 upon for addresses, beginning with Dr. Brierly, of England ; after 

 which Dr. Ball, Assistant Secretary of Agriculture, Prof. Symons, 

 of the University of Maryland, and other speakers entertained us 

 until nearly midnight. 



Thursday was another full day. We visited truck gardens to 

 study blights, rots, mosaics, tip-burns, etc. ; peach orchards to 

 observe the effects of spraying ; apple orchards for cedar eradica- 

 tion; and the Antietam battlefield for its historic interest. In the 

 evening, there was a meeting for the discussion of local fruit 

 diseases held under the auspices of the Washington County Fruit 

 Growers, at which Prof. Whetzel discussed dusting and spraying, 

 and Mr. Charles Repp, of New Jersey, outlined some of the diffi- 

 culties of the commercial fruit-grower of the present day. 



We shall never forget the informal talk given by Dr. Brierly in 

 the peach orchard Thursday morning. The audience sat on a 

 shaded, elevated terrace looking out on a wonderful valley, while
