“ formation, ” or bed of sand into a “period,” while “inter- 
glacial episodes are profusely scattered through the whole, appa- 
rently with the sole object of finding what Mr. Croll says must 
have happened.” 
Mr. Reade cannot accept the theory that the Till is wholly sub- 
aerial, and formed under land ice. It seems to him “ most 
unphilosophical first of all to attribute the planeing, grooving, 
smoothing, and striating of the whole surface of the land to ice, 
and then to make the very same agent, without any apparent 
reason for the change, deposit a mass of Till in the same places, 
sometimes reaching 162 feet thick.” 
Essay on the Artificial Propagation of Anadrotnous Fish other

Prize Essay, National Fisheries Exhibition, Norwich, 1881, on 
the Utilisation of Localities in Norfolk and Suffolk suitable 
for the Cultivation of Mussels and other Shell-fish. By C. 
W. Harding, Assoc. Inst. C.E. King’s Lynn : Thew

These two essays, courteously forwarded us by the author, are 
valuable contributions to the good work so ably conducted by the 
late Frank Buckland. 
We must, in the first place, enter our protest against the word 
“ anadrcmous ” as a piece of utterly gratuitous classicalism. 
Its exacft English translation, “ up running,” would answer the 
same purpose, and would be more easily remembered by that 
large majority of the public (including multitudes of naturalists) 
who have either never learnt Greek, or who, like ourselves, have 
had to throw it overboard to make room for more important 
matter. 
Mr. Harding announces the important conclusion that “ when- 
ever the tidal river fisheries have been more or less exhausted, 
the sea-fish proper, which at certain seasons of the year approach 
the coast, have fallen off in equal ratio.” From the information 
to which we have access we have little doubt but that this view 
is corredt. 
The author’s plea for the enadlment of a close time for all 
fishes, and for in general preventing fishermen, in their short- 
sighted greediness, from killing the goose which lays the golden 
eggs, is just and proper. Alternate periods of glut and scarcity, 
in any trade, are bad for producer and consumer, and good only 
for monopolist middlemen. Most of all is this the case with a 
perishable article such as fish.
