gastroduodenitis, which means intestinal disturbance from indi- 
gestion, that the food was not digested at all, that there was a 
sort of stoppage in there which produced probably abdominal 
colic in the fish and reflexly caused the heart to peter out, and 
subsequent death. It is well to remember that sort of thing be- 
cause I believe you can eradicate a great deal of it by influencing 
your foods before you put them into the water. 
There are other foods that are most excellent, and they are 
natural foods, if they can be obtained. The first one, and one it 
seems to me I have not heard many people speak of yet, is mag- 
gots; and there are maggots of all sizes. It is easy enough to 
hang somewhere in the course of a brook, upon a bending bush, 
a piece of meat, or a piece of fish, and allow the maggots to form 
and drop into the water; these are taken very eagerly by every 
sort of fish that swims, but I think that the trout particularly 
like them. The land-locked shrimp are to me one of the most 
important food for fishes, and one of the most dainty things that 
the fish can feed on; but it seems very hard work to know how to 
get them. I have been trying fruitlessly to get some of them. 
The land-locked shrimp is the most delicate of piscatorial bits 
for fishermen, and is the one food supply that if you get too 
many of them interferes with the sportsmen, because it feeds the 
fish so well that they will not come up to a fly. That is the trou- 
ble in Sunapee Lake, where perhaps so far as variety goes I do 
not know a place in the world that has as many different kinds 
of fish hving in its waters—black bass, pickerel, land-locked 
salmon, German trout, the Loch Leven trout, and the Sunapee 
trout, along with white perch, and all the different pond fish. 
Now these are all fed tremendously well on the land-locked smelt. 
The trouble in ponds such as I have is that they are not deep 
enough to raise these land-locked smelt in. You must have depth 
of water. They like to live in from fifty to seventy-five feet of 
water, and if you do not get cooling water for them to live in 
they are simply eaten up very quickly and your food supply is 
gone. 
We talked yesterday about ponds in a good many ways, how 
to build them, ete., we went over that subject very carefully. I do 
not know as I have a great deal to add, but perhaps there are one 
or two suggestions that I found of use in some ponds that I
