The drainage eastward from the great north and south 

 divide into the Delaware river, is also divisible into two sys- 

 tems. 



The north and south watershed splits as it goes south- 

 ward. Its main branch keeps due south. The other veers 

 off southeastward, and keeping rudely parallel to the Dela- 

 ware (6 to 7 miles west from it) passes into Pike county and 

 ends in a long narrow ridge at the Delaware river near 

 Lacka waxen. 



The streams on the eastern slope of this subordinate 

 watershed are mostly small, and descend with a very rapid 

 fall directly to the Delaware. They are the following be- 

 ginning at the north : 



Str aw def s creek, heading up against Starrucca, and flow-

Chehocton, heading up against Starrucca, in Preston, and 

 flowing northeast to the Delaware at Hancock. 



Big Equinuak heads against the tributaries of Lacka- 

 waxen, and also flows northeast to the Delaware at Equi- 

 nunk. 



Little Equinunlc takes its rise in Duck Harbor Pond at 

 the north-east line of Lebanon Tp. and descends at a very 

 rapid rate north-eastward to the Delaware. 



Holisters, Cashe* s, and Calkin's creeks flow eastward into 

 the Delaware in Damascus township. 



Mast Rope creek drains the southern portion of Berlin, 

 through the northeast corner of Pike county to the Dela-

The western slope of this water-shed as well as the eastern 

 slope of the main north and south divide (Moosic mount-
