the roads be picked over, in central Suffolk, fragments of many 
geological strata with fossils — all rounded, scratched and water- 
worn — can be readily found. These must have come at least 
from the midlands, i.e., from higher ground. At Filey, again, 
on the Yorkshire coast, between Scarborough and Flamborough 
Head, boulders of many materials may be seen scattered about 
as the cliffs are wasted away. 
To prove the enormous extent to which glaciers “ grew ” in 
the glacial epoch, if the tourist, when at Neuchatel, will walk 
to the top of the hills behind the town, he will find a wood. In 
this are numerous blocks of granite, &c., resting on the yellow 
limestone of the Jura range. One, known as Pierre-a-Bot, is as 
big as a cottage. Now they all must have come from Switzer- 
land, travelling on ice some 600 feet thick across the lake and 
valley of Geneva, till they were stranded where we now find 
them. 
The reader wdl gather that as an element of scenery we must 
find the ice in existence, as in Greenland and Switzerland ; but 
the effects left in Wales and Scotland are not conspicuous, 
unless one knows what to look for. Henceforth the tourist 
should make a point of looking out for the above-mentioned 
features, and he will soon discover them for himself ; and then 
he will be able in imagination to picture Snowdon, Cader Idris 
and Ben Nevis, &c., to resemble Mount Blanc and other Swiss 
mountains, as bearing a continuous mass of ice all over the 
higher regions and thrusting out great tongues of ice down the 
slopes into the valleys below, and thence out to sea, sending off 
icebergs to float away gradually, continually dropping their 
burdens of rock and finally disappearing. 
We have now completed our survey of the principal agents 
concerned in making scenery. My object has been to call 
attention to facts of nature and to excite an interest, if possible, 
in all who travel about to observe everything they can and 
verify all that they have elsewhere learnt.

Who's Who? 1900. Messrs. A. and C. Black. Price 3s. 6d. net. 
When a work of reference has reached its fifty-second year of issue it needs no 
introduction, and its longevity is its best recommendation. But in spite of its 
serviceable, flexible red cloth cover. Who’s Who? may well be styled an evergreen, 
for, though fifty-two years old, in completeness and correctness it shows itself 
still vigorous and up to date. Naturalists, like other folk, may well be interested 
in what are virtually autobiographical notices of their fellows, whilst the pre- 
liminary lists of officials of all kinds are invaluable to everybody.
