may be represented as follows:

O dear me ! pee — pyu—pyu 
This is sung very slowly and the second half with a curi¬ 
ous intonation, suggesting memories of “mal de mer.” I 
have only once heard the full song of the white-crowned 
sparrow. It is superb in form and quality, more nearly 
resembling that of the vesper sparrow than any other. 
Dike that it defies transcription.

Limestone and Bog Iron Ore Near Manchester 
The Archaean Rocks of New Hampshire do not contain 
much limestone, but in a few places it is found, showing 
that there were a few hollows in the Taurentian ocean bot¬ 
tom in which the animals of that time left their skeletons. 
In the northeast corner of Amherst, in a small valley through 
which trickles a tiny brook, is found a small outcropping 
of carbonate of lime. It was briefly described by Dr. Jack- 
son in his early work on the Geology of New Hampshire 
For a while it was quarried and burned but was finally 
abandoned and is now largely covered with soil and rocks 
that have been dumped into the excavation. The lime¬ 
stone is so crystalline that probably no fossils could be found 
in it. 
A few miles northeast of the limestone deposit, in the 
town of Bedford, is a small deposit of bog iron ore which is 
of fine quality but not very extensive. This is said to have 
been worked some in the past.
