backbone of that mountain to the high spur south of Bealetown; thence 1½ miles southwest across the Liberty valley to the Medina crest of the southern division of the mountain and with it 41 miles west to the Lack township corner. The area of the township will not fall far short of 50 square miles.
McCoysville and Reeds Gap are both flourishing little villages on the north side of the synclial and upon opposite sides of the North limestone ridge, while Bealetown (Honey Grove) and Waterford are two additional villages in the southern portion of the township, both lying south of the Southern limestone ridge on small tributaries of Tuscarora creek.
This stream is again the most important avenue of drainage in the township, receiving accessions from all parts of the township by streams of considerable size. Entering from Lack township it cuts through the South Limestone ridge north of Waterford and washes its south base for the next two miles where it again cuts back into the slate valley to wind its course eastwards and northwards across the valley near to the center of the township.
Here it receives its most important tributary, Willow Run, a three-pronged stream watering the main central slate valley, as well as receiving a tributary from the Shade mountain through Reed’s Gap, and with the parent stream makes a considerable creek flowing eastward for 2 miles to the Spruce Hill township line.
Within one-half a mile of that line it receives the McCoysville branch from the north, which, after cutting through the Academia anticlinal ridge crosses the plain of upper Salina shales and cuts through the North Limestone ridge just east of McCoysville.
The geological column of rocks exposed in this township extends from the Hudson river No. IIT slates, in the eastern end of the Black Log valley, upwards to the Hamilton and Genessee No, VIII sandstone, shales and slates, contained in the main basin of the township.
The structure is diversified and extremely interesting. On
