level is indicated by a dotted line. Along the Fifteen-mile Falls, 
between John’s River and the mouth of the Passumpsic, the region 
of the upper falls, according to Mr. Upham, is without regular 
terraces ; but that of the lower, below Lower Waterford, has hills 
and terraces of stratified drift which reach in some places a level 
of 200 feet above the river. So great a height here favors the 
view that the 130-foot level at and above Lancaster is the most 
nearly right. My personal observations in the valley beyond 
arnet were limited to the single locality of Lancaster.

at least the lower of the two terraces above-mentioned was

of it two miles no rth along the BR il valley (near the

At Haverhill the “ peach ele poe of Mr. Upham 
has a height, as he states, of only 83 feet. But the true normal 
upper terrace is over three times this height, as is shown by the 
position and extent of the large Haverhill ‘terrace-plain as well as 
the so-called “ delta-terrace” of Oliverian Brook. 
The terrace-plain on which the village of Haverhill is situated 
has great breadth, and continues along the — ut for two

consists of sand and sandy loam with some small pebbles, but 
becomes more stony toward the hills. 
Mr. Upham alludes to the plain, but excludes it from the true 
serraces, Stating that it is “a terrace-like area of ¢i/.” He says 
that “at about one-fourth mile southwest from Haverhill village
