358 WEST VIRGINIA EXPERIMENT STATION. 



depositing eggs, There was not sufficient evidence, however, 

 that this or any other insect had caused the death of the tree. 



Between May 5th and 7th I made a trip by horse and buggy 

 through Hampshire county, from Romney to Ice Mountain and 

 returned by another route. This is distinctly a pine region 

 where the scrub, pitch, yellow, table mountain and white pine 

 all occur more or less common. Here a great amount of tim- 

 ber had died during the epidemic of 1892, but at the time of 

 this visit, very few trees indeed were dying; no more in fact 

 than would naturally occur in any pine forest. 



CONDITIONS IN THE SPRUCE, 



The spruce forest in Tucker county was visited on May 8th 

 and 9th near Davis, where the spruce timber was found in a 

 healthy condition. Here, as in the white pine, the extensive 

 cutting of timber furnished an abundance of food and places to 

 breed for the spruce bark beetles, in stumps, logs and tops, so 

 that there was no occasion for them to attack the living trees. 



The spruce forest near Pickens, in Randolph county, was 

 visited on June 22d, and no spruce trees whatever were found 

 dying. In fact, it was necessary on account of the absence of 

 injured and recently felled trees, to girdle a number of trees in 

 order to make the conditions favorable for the colony of Clerids 

 that was located there. But very few trees had died from the 

 attack of the destructive bark beetle, in this isolated section of 

 the spruce area. 



CONDITIONS IN THE MAYFIELD HILL GROVE. 



The Mayfield Hill Grove was visited, on Sept. 2d when old 

 mines of the destructive bark beetles were cut from some of 

 the living trees that were covered by two annual growths or 

 layers of wood, and the galleries of the turpentine bark beetle 

 were found that had been covered with one layer. 



One dying tree was found that bore evidence of having been 

 killed by Tomicus calliyraphus and Tomicus cacographus 

 which occurred in the bark in large numbers, the parent bee- 

 tles having entered the living bark, as indicated by the balls 

 of turpentine. All of the other trees were, however, in a
