In 1905 Bulletin 3, also by Cook and Horne, on " The Coffee Leaf- 

 miner and Other Coffee Pests," appeared. 



Mr. W'. T. Horne, in September, 1906, succeeded Doctor Cook as 

 Chief of the Department of Plant Pathology. In May, 1907, Bulle- 

 tin 7, entitled " Insects and Diseases of Corn, Sugar Cane, and Related 

 Plants," by Cook and Horne, was published. Following the pro- 

 motion of Mr. Horne, Mr. J. S. Houser was appointed assistant in 

 the Department of Plant Pathology to fill the vacancy, having served 

 prior to that time as assistant entomologist in the Ohio Agricultural 

 Experiment Station. ' The following year, 1907, a position of second 

 assistant was created and Sr. Sebastian Pla was appointed to the 

 position. Bulletin 9, " Insects and Diseases of the Orange," by Cook 

 and Plorne, was published in February, 1908, and in May, 1908. 

 Bulletin 12, entitled " Insects and Diseases of Vegetables." In July, 

 1908, B.ulletin 15 by Mr. Horne, on "Bud Rot and Other Diseases

 Houser published a paper on " The ' Candelilla * or Leaf-miner of 

 Tobacco, Phthorimaea operculella ZeW." In the same publication there 

 appeared an article on the " Damage to Pines in Cuba Due to Dio- 

 ryctria sp. and other Lepidoptera," by Horne and Houser. 



Mr. Houser retired from the Station in the early part of 1909 and

 personnel. The next bulletin containing information on economic 

 insects was No. 20, published in July, 191 1, entitled "Insects and

 Pathologist was appointed and a separate department for this work 

 temporarily created, Sr. Cardin remaining in charge of the Depart- 

 ment of Entomology. Mr. H. C. Eagerton was appointed Assistant 

 Entomologist in November, 1914, but remained at the Station for only
