and northern Scotland to Inverness, although drumlins were 
constantly looked for, none were seen and the outlook on each 
side from the railways is generally extensive, ranging miles 
away, over cultivated or pastured tracts, without woods to 
conceal the glacial drift and the minor topographic features. 
Returning southward along loch Ness and the Calendon- 
ian canal, with its other lochs, in the Great Glen of Scotland, 
which divides the mighty mountains of the Highlands by a 
pass only about 100 feet above the sea, to Fort William, and 
thence continuing southward by the recently built West 
Highland railway, by lochs in deep mountain gorges, over 
Inroad, high moors bearing many marginal moraines, and 
through the grand and beautiful scenery of loch Lomond, loch 
Long, Gare loch, and the Clyde estuary, still I saw no drumlins. 
But as our train came into the northern suburbs of Glasgow, 
passing Mary Hill, Possil Park, and Cowlairs stations, many 
drumlins were observed, closely adjoining our railway on 
each side and promising, by their admirably typical develop- 
ment, that they were part of a very interesting drumlin dis- 
trict. 
During the next three days, July 3rd to the 5th, of last 
summer, I walked nearly fifty miles in the city of Glasgow 
and its near environs to map its seventy-five and more drum- 
lins, which have the same irregular distribution and frequently 
compound grouping as in southern New Hampshire and 
northeastern Massachusetts, where I had mapped many of 
these remarkable drift hills, the first so delineated and par- 
ticularly described in America, twenty years ago.''' In more 
recent years the thorough exploration by Prof. George H. 
IJarton has recorded the detailed distribution and special char- 
acters of the fifteen hundred drumlins of Massachusetts, a 
state which has many tracts of these hills similar to Glasgow, 
1:)Ut scarcely any superior. The Glasgow drumlins are closely 
like those of New England in their outlines, being smoothly 
(3val, and trending east-southeasterly in parallelism with the drift 
transportation and striae; in their material, which is the usual 
till or boulder-clay, rarely containing a nucleus of rock; in their 
areas, from a quarter to two-thirds of a mile long, with mostly
