larger fish during their stay in the river do not feed, and 
do not remain very long after they have deposited their 
spawn. 
Plants have been made of the shad in the Sacramento 
River in California, with the astounding result that they 
are now found in every river of the west coast from 
California to Puget Sound. This success has suggested 
the idea that it might be worth while to experiment on 
their introduction into Lancashire rivers. Before under- 
taking the placing of any American shad in our rivers, it 
is desirable, 1f not already done, that accurate records of 
temperature be taken in the Ribble, Lune, and Kent, 
during the months of March, April, and May, to see if our 
temperatures are high enough for the shad. 
It would certainly be a great addition to our food supply, 
and, although it may be a little trouble, yet, now with 
refrigerating chambers, I do not see that there could be 
any real difficulty in getting a supply of impregnated eggs 
brought over from the United States.
