and the eruption have resulted in this case from the Phlebotomus 

 bites of Sept. 17, 1913, to which were added a half dozen bites on 

 the night of Nov. 6, 1913- It is practically certain that only one 

 species of microbe was transmitted during the bites of the Phlebo- 

 tomus. ,. . 



The injection of neosalvarsan produced a slight temporary diminu- 

 tion of the Bartonia bodies, according to Dr. Barton. They shortly 

 increased again. It is indicated that this drug, in larger quantity and 

 frequently repeated, is a specific against the disease. 



A complete history of this case will eventually be published by Dr. 

 Barton. CHARLES H. T. TOWNSEND, Chosica, Peru, January 26, 1914. 



Control Work Against Forest Insect Depredations in the Hetch 

 Hetchy Watershed of the Yosemite National Park (Coleop.). 



Special investigations by the experts of the Department of Agricul- 

 ture have shown that as much as 95 per cent, of the timber in some 

 of the canyons and valleys of the Tuolumne River, which is to supply 

 the water for the Hetch Hetchy project, has been killed by bark-bor- 

 ing insects. 



The areas in which practically all of the timber has been killed, 

 some of it many years ago, are Jack Main Canyon and Matterhorn 

 Canyon. It was found that the forest growth of the entire water- 

 shed was more or less affected, and that the destructive insects were 

 killing a great amount of timber from near Tenaya Lake through the 

 forests surrounding Tuolumne Meadows to and through Virginia 

 Canyon. 



This alarming condition, affecting as it did the scenic beauty of the 

 area north of the Yosemite Valley and its consequent effect on the 

 water supply and general economy of the Hetch Hetchy project, pre- 

 sented a problem of great importance. 



As soon as the matter was called to the attention of the Secretary 

 of the Interior in the fall of 1912, he appealed to the Secretary of 

 Agriculture for such advice and assistance as his Department could 

 render through the expert who has charge of the forest insect branch 

 of the Bureau of Entomology. 



The matter received the required prompt attention and arrange- 

 ments were soon made for active warfare against the depredating 

 beetle. A plan of procedure was outlined by the expert and recom- 

 mended by the Secrtary of Agriculture to the Secretary of the In- 

 terior. According to the plan, the Interior Department was to allot 

 the required funds, the control work to be carried on under the im- 

 mediate supervision of an entomological assistant of the Bureau of 

 Entomology. This plan was adopted and the work was started just 

 as soon as the weather conditions permitted in June, 1913. 



The areas near Tenaya Lake and in the Cathedral Basin around 

 Tuolumne Peak to the Tuolumne Meadows were carefully cruised for
