DELAWARE VALLEY ORNITHOLOGICAL CLDB. 11 



forget our walk up the first seven miles of that valley! We 

 left Cross Forks about 9 o'clock in the morning, and making 

 due allowance for an hour and a half's rest in the shade of a 

 farm house, while we refreshed our weary bodies with a good 

 lunch of milk and pie, it took us tiU 2 o'clock to reach the edge 

 of the forest land. And during those four odd hours the heat 

 was terrific, the dust was fearful and the shade was nil. In- 

 deed, if it had not been for two or three little roadside springs 

 — remains of the original primeval forest, and the cooling condi- 

 tions which it always brings with it — we would hardly have had 

 the heart or courage to continue. Scarcely a bird was to be 

 heard or seen. But suddenly, when some three miles south of 

 Oleona we struck the edge of the green timlier, all this was 

 changed. The scenery now became wild and beautiful. For 

 the most part the hills rise steeply on either side of the creek, 

 but here and there the valley widens and the road takes us past 

 green meadows and a group of neat little farm buildings. Back 

 across the hills for miles stretches the unbroken primeval forest. 

 Here everything at once became cool and green again. More- 

 over, hardly had we entered the woodland before we heard the 

 cheery little song of the Snowbird, and a beautiful little nest 

 with four eggs was found in the bank along the road-side. This 

 species, as well as most of the northern warblers which we had 

 observed at Tamarack Swamp, continued to increase in num- 

 bers, until, in the four miles of timber-land between Oleona and 

 New Bergen, they became very common. At Oleona, rather to 

 our surprise, we again heard a whippoorwill. It was not, how- 

 ever, until we had passed this little village, which, by the way, 

 consists of a small country tavern and two houses, and was 

 named after the famous Ole Bull who settled in the County 

 about 1852 — that we met with perhaps the most interesting of 

 our discoveries in the bird Line. This was the Mourning 

 Warbler, which proved to be a conmion species along the road- 

 side and up the mountain divides all the way between Oleona 

 and New Bergen. In this magnificent stretch of woodland we 

 also observed Rose-breasted Grosbeaks and a single Water 

 Thrush, both species not heretofore noted. Winter Wrens were 

 also occasionally heard. On the other hand, Olive-backed
