its practical bearing and his company was a great delight. The 

 next stop was made at Wilkes-Barre. In company with Mr. J. E. 

 Patterson a trip was taken to Glen Summit Springs, about nine miles 

 south of Wilkes-Barre. In these trips frequent stops were made and 

 a dozen or more investigations were undertaken. Luzerne county 

 did not furnish a single specimen that gave any indication of the 

 presence of the blight. 



At Scranton on the Lackawanna river, a tributary of the Susque- 

 hanna, there is little or no chestnut growth. Valuable information 

 was obtained from Mr. T. J. Snowden, a lumber dealer, as to the 

 character of what little forest growih remains in that part of the 

 State. In his lumber yard there were tour hundred chestnut posts 

 from six to eight feet in length. These had been cut at Hawley near 

 the border of Pike county. Having been recently cut, the bark which 

 was on the posts would have given evidence of the disease had It 

 existed. There was no sign of the blight on any of these posts. 



The next stop was made at Carbondale in the northeasterly part of 

 Lackawanna county. Here as at Scranton, the lack of forests in gen- 

 eral, and especially of chestnut trees, precluded an extended investiga- 

 tion. Going eastward over the divide between the Lackawanna river 

 and the Lacka waxen creek or in a broader sense over the highland 

 which separates the watershed of the Sr,s:iuehanna from that of the 

 Delaware river, the work was taken up at Honesdale. No chestnut 

 growth could be found within ten miles of Houesdale, was the in- 

 formation received from Mr. Kreitner of that town. Since the writer 

 had found the blight at Mil ford on the Delaware, in Pike county it 

 became an important question to ascertain if it had spread westward 

 and been carried into the upper portions of the Susquelmnna valley. 

 The disease exists at Mill'ord and farther north to within three miles 

 of Matamoras, Pa., opposite Port Jervis, N. Y. With Mr. E. T. 

 Riviere of Milford, infected trees were found to the west and again 

 to the south of Milford. Specimens of the blight were taken about 

 one mile from the Camp of the Vale Summer School of Forestry on 

 the estate of Mr. Gilford Pincliot, Chief of the U. S. Forest Service. 



To sum up for the Susquehanna valley. The chestnut tree blight 

 was not found north of South Mountain. It was found in several 

 localities south of South Mountain along the Susquehanua and on 

 the watershed lying to the east of the river. 



In the Delaware valley infected chestnut trees were found at Em- 

 breeville in Chester County, on the Brandy wine, a tributary of the 

 Delaware river; at Haverford in Montgomery county; at Trenton, 

 N. J., and across the river at Morrisville in Bucks county; near Eas- 

 tern in Northampton county; and at Milford and Matamoras in Pike 

 county. Nowhere in Pennsylvania has the blight become so virulent
