every facility for prosecuting the work, furnishing livery, tools, 

 guides, etc. 



April 22, I arrived at Grants Pass, Oreg. , and investigated the con- 

 dition of the forests in relation to insect depredations in the moun- 

 tains north, northeast, and southwest of the city. The most important 

 feature found here was the prevalence of the same species of Dendro- 

 ctonus discovered at McCloud, and many hundreds of trees which had 

 evidently died from its attack. In one place a group of over thirty 

 trees were dying. These were carefully investigated. The living and 

 dying bark were found to he infested with different stages of the 

 Dendroctonus, and quite conclusive evidence was found that the 

 death of these trees was primarily due to the attack of this bark- 

 beetle. In another section it was found that the same species had 

 attacked the sugar pine, Pinus lambertiana, which, with Pinus ponder- 

 osa, are among the most valuable timber trees of the Northwest. The 

 discovery was also made here that this Dendroctonus was not attracted 

 to felled trees, as is the case with most other Scolytids, but is attracted 

 to, and freely breeds in, trees that have been girdled by the settlers 

 and farmers in the process of clearing the land; and that these trees 

 form nuclei for the multiplication and spread of the pest to the healthy 

 trees in adjoining forests. 



Leaving Grants Pass on the 27th, I spent a few hours profitably col- 

 lecting specimens near Albany and Corvallis, arriving at the latter 

 place in the evening. In accordance with instructions I visited the 

 agricultural college and experiment station here on the 29th, and 

 called on the entomologist, Prof. A. B. Cordley. 



The next day, April 30, accompanied by Professor Cordley, I pro- 

 ceeded to Newport, Oreg., at the mouth of Yaquina Bay, where I 

 spent the day investigating the insect enemies of the trees of this most 

 interesting section. Among the important observations made here 

 was my discovery of a Scolytid enemy of the white alder (Alnus rhom- 

 hifolia) , which is very common and quite in j urious to this tree. Another 

 species of Scolytid, representing an undescribed Hylesinus, was found 

 to be common in the bark of recently felled hemlock. These observa- 

 tions had the added interest of being the first record of Scolytid bark- 

 beetles infesting alder and hemlock. An undescribed Dendroctonus 

 was found in the bark of Picea sitchensis, and several other Scolytids, 

 which are undescribed, were found in this spruce and in Pinus contorta. 

 I was also fortunate in finding in a cone of the last-named tree Mr. 

 Schwarz's rare and interesting species, Pityojihtliorus coniperda, the 

 occurrence of which on this coast is most remarkable. Taking it all in 

 all, this locality proved to be one of especial scientific and economic 

 interest. 



May 1, we returned to Corvallis, and the following day, accompanied 

 by Professor Lake, horticulturist and botanist of the college and sta-
