The Seabord Pipe Line survey’ line commences in the Oil Region of 
Western Pennsylvania, in the Valley of the Alleghany River, at a point 
one and a-half miles below (south of) Monterey Station on the Alleghany 
Valley Railroad ; takes a nearly straight course over the high lands of In- 
diana and Cambria Counties; descends the face of the Alleghany Moun- 
tain; crosses the mountains and valleys of Middle Pennsylvania; the 
South Mountain range ; the red sandstone plain in front of them, and 
oe hills of Middle Maryland to Baltimore; a total distance of about 
228 miles, = 1,202,828 feet. 
It passes about fourteen miles south of the county town of Indiana ; one 
mile south of Carrolton in Cambria County ; crosses the Pennsylvania 
Railroad at Elizabeth Furnace; the Broad Top Railroad at McConnells- 
town; passes through Orbisonia, Shade Gap, Roxboro’, Shippensburg, 
Gettysburg ; passes one mile south of Littlestown ; two and a-half miles 
south of Westminster ; one mile south of Reisterstown ; follows the ridge 
between Patapsco Falls and Guyron’s Falls, and terminates on Curtis’ Bay 
two miles south of Canton, on an inlet of Chesapeake Bay at Baltimore. 
REMARKS. 
Tn the column marked /\ the distance from starting points B M are 
given in feet, measured on the ground (not horizontally). 
The elevation is given in the second column in feet and hundredths. 
Nore. The decimal point in the 1st, 5th and 7th columns divides the 
distance into lengths of 100 feet. Thus: 98.35 = 9,835 feet, &e. 
The courses given in the second column show the general direction. 
The line run varies from the general direction in many places, but is sel- 
dom more than from one to two hundred yards to right or left of the gen- 
eral course, and in most cases less. 
The distances in the fourth column are the distances of a number of 
shorter courses taken by scale from the plot. 
The columns of Maxima and Minima give the undulations, being ordi- 
nates at extreme elevations and depressions, or where there are changes in 
the slope of the ground. 
Any further information desired may be obtained from B, F. Warren, 
734 N. 20th Street, Philadelphia. 
The degrees and minutes of courses begin with 0° at north, running 90°
