Of late years the social or community interest became 
uppermost with him and he believed that the schools 
could do much to repair the wreckage of the War ; he 
emphasised always the need for co-operation and 
pulling one’s weight, for choosing the high path, for 
steadfast devotion to duties and. leaving rights to 
take care of themselves. 

The last evening of Sanderson’s life was spent 
with the present writer. He had attended the Rotham- 
sted annual function and had obviously enjoyed it. 
After the visitors had gone we sat talking and, as 
always, he soon came to his plans for the future. 
He was delighted that his long-desired Chapel was 
to be built. It was to be the centre of the school life 
and as beautiful and dignified as he could make it ; 
not only with the beauty of stone: it was to be also 
in a wonderful garden—a miniature Kew, as he said. 
In the windows were to be the great calls to a high 
and noble life. Most of all he was delighted with 
Lady Scott’s statue of the bright-eyed, eager-hearted, 
expectant boy—“ Here am I, send me”—the type 
he wanted to send out to remake a broken world. It 
was the man himself speaking of his hopes and ideals, 
as few would care to do to another man—ideals of 
fulness and richness of life based on beauty and noble- 
ness of living. For these we wished our boys to strive 
and so we had entrusted them to him. . 
Sanderson had thoroughly enjoyed life. He early 
found what most men desire—a great cause on which 
to spend himself, and to which he could give once 
and give all. As the years passed they had but 
mellowed him, bringing out his kindliness and _ his 
rich rare gift of keeping touch with youth. When the 
news of his death was told to the school there fell a 
great silence. It had been the homage given him in 
life when he rose to speak; it was given him now. 
But their abiding feeling was one of thankfulness for 
the life which had so truly moulded theirs, and of 
certainty that this was not the end. The triumphant 
song “‘ Let joy and praise to Heaven rise”’ can rarely 
have been more wonderfully sung than by the boys of 
Oundle when he was carried from their midst.

[JUNE 2, 1923 
abridgment entitled “The Elements of Engineering 
Geology.” The volume includes an account of the 
general principles of geology and petrology, apparently 
with the intention that the book should suffice for the 
geological needs of engineering students. It, however, 
includes no sections on stratigraphy or paleontology, 
some acquaintance with which is generally regarded 
as essential to a geological course in engineering. 
Knowledge of these subjects would be necessary to 
the student who would benefit by the long chapter 
on ore deposits. 
The book may be highly recommended to British 
students of civil engineering owing to its clear treat- 
ment of many important problems and its instructive 
series of maps and illustrations, though its value 
to them is inevitably lessened by the fact that 
most of its illustrations are taken from American 
example and literature. The nomenclature is also 
American in such cases, such as “gumbo,” and the use 
of “‘diabase” instead of “dolerite.” The attribution 
of all China clay to weathering is a conclusion which 
is emphatically rejected in Europe. The statement 
on p. go that an oil shale to be of value should yield 
from 30 to 60 gallons of oil per ton in addition to 
ammonia, is not in accordance with experience in 
Scotland, where shales containing 20 gallons or even 
less have been profitably worked. Melting snow is 
said rarely to affect large streams; this is cer- 
tainly not true of some large rivers in Europe and 
Asia, where the spring floods are due to this cause. 

The authors use the unlucky term “ corrasion ” for 
mechanical excavation by rivers and “ corrosion” 
for solution. The American use of distinct terms 
for the basal and lateral wear of the streams 
had: much to commend it; but “corrasion” as in 
the line “ wealth corraded by corruption ” means to 
“scrape together,’ and corrasion was first used in 
the sense of corrosion apparently by a misprint. In 
regard to nomenclature it is also to be regretted that 
the authors in a book on economic geology use the 
term “mineral” in the sense of ‘“ mineral species ” 
or ‘simple mineral’? and thus exclude coal, slate, 
most ores, oil shale and mineral oil from the category 
of minerals. 
The chapter devoted to the coastal topography 
of the United States is particularly interesting and 
well illustrated ; the difference of the problems from 
those which have to be dealt with by the British 
coastal engineer is shown by the absence in the book 
of any reference to groynes. In spite, however, of — 
the book being mainly adapted for American colleges 
it may be warmly recommended to British civil — 
engineering students. J. W.3G3 ae
