till, like that which I have described as at ■’present
existing at Bodo.
As either of these deposits consists of the total
glacial debris minus that portion washable away
by water, they are almost identical in structure,
although their origin may be different. Without
going further into details, I think I have made out
a fair case for my client, this “ glacier gravel ” or
“ boulder sand,” as being worthy of respectful
attention and careful study by geologists.
I may add that it exists somewhat abundantly,
and with many modifications, in England,
Scotland, Wales, and Ireland. After my first visit to
Norway, and during a few years’ residence on the
Hope Mountain in Flintshire, I very carefully
studied the details of the glaciation of the
surrounding district,* was much puzzled by a similar
deposit, and, suspecting its origin, looked especially
for it in Norway. But for this I might again have
missed it on the Dovrefjeld, as it is covered almost
completely with mossy vegetation. It is, however,
well seen at the roadsides, especially where it has
been cut through to form the new roads.
* Some of the results of these observations were stated in a paper
“On the Ancient Glaciers North and East of Llangollen, and more
particularly in the neighbourhood of the Hope Mountain,” read at the
British Association, 1865. For abstract, see p. 77 of ‘Transactions of
the Sections ’ for that year.
