Beis) Tield Notes 
visiting a daughter at Curbar, near the Duke of Devonshire’s 
moors, and hearing of two ladies being attacked and driven 
back by a Grouse, my son-in-law and I took a stroll on the moor, 
to verify the statement, and as soon as we reached the bird’s 
beat, we heard a w-r-r-r of wings, and a fine cock grouse alighted 
on the path in front of us, and disputed our passage with the 
cry of ‘“‘ Go-back”’ or ‘‘ get-out,’’ but which I think is’ “‘ Gar- 
ouse,”’ probably the origin of the bird’s name. It fought with 
my stick, which I tried to hook round its neck, and jumped at 
my friend’s straw hat, which he held in his hand, like a bantam 
cock, and kept up the game until we had passed over his 
ground, when he flew back to cover in the heather. Confirma- 
tion of this may be had from Mr. Peet, the head keeper, who 
lives close to the place, and who, I understand, had reared it 
with his chickens.’—R. FORTUNE.

The Earth and its Story, by A. R. Dwerryhouse, D.Sc., F.G.S. London: 
CaEPe elles O4) Ds 5) lle. 
Dr. Dwerrynouse, who is a frequent contributor to the pages of The 
Naturalist, has written this volume in order ‘to lay before the general 
reader, in a simple and interesting manner, some of the facts which are 
known about the earth upon which we live, and the processes of change 
to which it is constantly being subjected.’ It contains in Part I.* a series 
of articles on Wind and Rain, Brooks and Rivers, A Glacier, The Sea, 
The Floor of the Ocean, Volcanoes and Earthquakes, Fossils, ete ; and 
in Part II., descriptions of the rocks and their contents, beginning with 
the Archaean. Each chapter is a separate essay on the subject given, 
and for the most part is written in simple language. In ‘ The Interior 
of the Earth,’ however, it is much too ‘ deep’ for us—though we may not 
be a properly qualified “ general reader.’ For example: “ Now, from the 
equation on p. 148, we have 
Bx B E x1 E 
f=G a2 = G72 also w= G ince R2 
and from these two equations we get a third, from which we can calculate 
the value of E, because we know the value of all the other letters which 
the equation contains. 
w ixe2 
De 2 aE 
Thus the mass of the earth can be determined.’ 
Personally, we don’t believe it, though the genera! reader can do as he 
(or she) likes. Similarly, we are not quite sure that (speaking of the 
formation of columnar basalt) ‘all the forces meeting along ab can be 
resolved into forces parallel to rf and 2/, and others acting along bf and af. 
The latter, being equal and opposite, would balance,’ etc. 
The volume is well illustrated, many of the photographs (by Mr- 
Godfrey Bingley and others) will be familiar to our readers. The coloured 
maps shewing the probable position of glaciers in the British Isles before 
the advent of the Scandinavian Ice-Sheet, and the condition of the British 
Isles at the period of Maximum Glaciation, are particularly interesting. 
A coloured geological map of the British Isles form the frontispiece.
