212 The Ainerican Geologist. October, isoa 
The surface of the country all around is strewn v.ith gneiss, and 
also with quartzite bowlders, which were traced continously from 
the moraine at Butzville southward to Washington. It is a matter 
of surprise that such pronounced glacial deposits should ever 
have been relegated to an unglaciated area. They are of the 
same nature as many of those which are made to do duty as por- 
tions of the terminal moraine. Although it was constantly in 
our minds, we were unable to see any chemical basis for separat- 
ing these deposits from those of the moraine, such as superior 
oxidation or ferrugination. It should be noted that the gneiss 
which somewhat dominates the deposits at Oxford Furnace is 
often hornblendie and is seamed with iron ore. 
Evidence of glaciation in several other parts of the triangle re- 
ferred to was observed, though surface features had to be relied 
upon, as cuts and excavations were commonly wanting. For a 
distance of eight miles northeast of Phillipsburg, the high ground 
of Scott's mountain was explored upon two different roads. 
Everywhere there was found at least a thin scattering of foreign 
bowlders — conglomerates and quartzites predominating — -while at 
several points there were notable accumulations of these, as at 
Harmony, a mile and a half east of Harmony, and two miles 
south of ]jOwer Harmony. Southeast of Phillipsburg also 
they are generally distributed, with special accumulations 
on the pass between Springtown and Hughesville at an 
altitude of 320 feet, a mile east of Carpentersville at 250 
feet, and for a distance of three miles on the north slope of 
Musconetcong mountain, south of Hughesville and Bloomsbury, 
at altitudes from 700 to 760 feet. Above this altitude, on the 
summits rising to 000 feet and more, only the local gneiss bowl- 
ders occur. This is the only locality where the ice-sheet is known 
to have reached Musconetcong mountain, though there are 
northern bowlders in the valley a mile or two west of New Hamp- 
ton Junction at an elevation of 450 feet. These latter bowlders, 
however, were not traced into connection with the deposits north- 
ward at Washington, and it is possible that they have suffered 
some water transportation since the retreat of the ice. 
So far as is yet known, the ice did not flow over any of the 
passes on Musconetcong mountain and down its southern slo{)e. 
A little stream has carried some of the Kittatinny mountain
