places I find liver is used. Curd, horse meat and mush at 
three place. Maggots, mussels, boiled fish and hens’ eggs 
are each used at different places. At four of the places 
natural food is very abundant in the waters and largely 
depended upon fora portion of the year. You are all 
familiar with these various forms of food, and I shall not 
make further reference to them except to touch upon the 
points of natural food and the mixture of vegetable and 
animal food for trout. No little was said in the meetings 
of 1891 and 1892 upon the former subject, and I should not 
now refer to it except that on the part of some an incredul- 
ity was expressed as to the possibility of producing an 
adequate amount of natural food for more than a few hun- 
dred fishes. The following letter from Mr. Andrews will, 
I hope, satisfy the incredulous on this point : 
WeESTGATE Housk, Guilford, England, May 6, 1893.— 
Dear Sir: In reply to yours of April 18, it gives me great 
pleasure to comply with your request, and if the following 
is of any use to you I shall be very glad. I presume you 
have kept a copy of your letter to me, and I therefore sim- 
ply answer your questions as numbered. 
1. I have two hatcheries, the principal one being at 
Guilford, with capacity for hatching between 3,000,000 
and 4,000,000 ova. The other hatchery is at my ponds at 
Haslemere, and is smaller. 
The principal rearing ponds, and also ponds for the 
larger fish, are at Crichmere, Haslemere, and are from 200 
to 300 feet above sea level. 
3. Temperature of the hatching water at Guilford is 
pretty uniform at 49 to 51°. Temperature at my ponds 
varies from 49° in winter to 56° in summer. Occasionally 
it rises 2 or 8° higher, but very seldom. 
The quantity of water passing through my Crichmere 
ponds amounts to nearly a million gallons per diem, and 
is only very slightly affected by a long drought and not to 
any visible extent. ‘The place is, moreover, not subject to
