inches length, into No. 5, and the 
larger, according to their sizes, into 
the other numbers ; and so on with 
Mo. 35.2; :1; 
Store-fish, procured elsewhere, 
if taken in summer, should be mov- 
ed in the night, in clean straw, 
wetted occasionally after they are 
packed ; except perch and pike, 
which can only be carried in clean 
river, or pond water. 
In removing fish from one pond 
to another, they should be first put 
into tubs of water, already prepared 
for them, and afterwards carried in 
buckets, without water. In taking 
pike or perch, great care must be 
observed to avoid raising mud in the 
water. 
In breeding ponds, all water 
fowls, as geese, ducks, &c. should 
be discouraged, and herons, in par- 
ticular, destroyed. If any white fish, 
as roach, dace, &c. should abound, 
they are tobe taken: and if therebe 
a spare piece of water for large pike, 
they should be put into it as food 
for the pike. 
Eels may be put, with advantage, 
into any, except the breeding pond, 
in lieu of perch, or some of each 
sort, ‘The most easy way of taking 
them, is by trimmers laid over night, 
baited with small fish, not with 
worms, otherwise they may catch 
the carp; or with a small thief-net 
baited with white fish. 
Common sewers and drains from 
the laundry are prejudicial to fish ; 
so are the leaves falling from trees 
in great quantities, which should he 
immediately raked out. 
The use of grains should likewise 
be ayeided in large quantities, as 
having little nourishment, whilst 
they are thus washei by the water. 
It seems better for the use of the

table, as well as more humane to 
kill fish designed for food by an in- 
cision with a sharp. pointed knife, 
or puncture made with a pin longi- 
tudinally, into the brain, about half 
an inch, or an inch, according.to 
the size of the fish, above the eyes. 
As this produces an instantaneous 
eflect, it would, probably, save the 
cruel operation of crimping or flay- 
ing fish whilst alive, as in the case 
of pike and eels. 
It is obvious, that this method of 
regulating fish, will apply, with its 
full effect, in larger spaces of wa- 
ter; it will, likewise, apply in a 
considerable degree tosmaller pieces, 
even where the change is but from 
a pond for the use of cattle, toa 
single canal in a garden; which, if 
narrow and Jong, may be divided 
by boards with some holes bored 
for the water to make a current 
through them. 
In situations near the great in- 
land manufactures, and near the 
turnpike-roads leading from an easy 
distance to the metropolis, water 
may be made, by this kind of ma- 
nagement, with little trouble or ex- 
pense, to produce a large annual 
rent. 
To those, who are yery curious 
in the flavour of their fish, another 
improvement is recommended, of 
castrating the male carp; the me- 
thod of performing. the operation 
may be seen by referring to the 
Gentleman’s Magazine, about forty 
years ago, which may readily be 
found by referring to the general 
index. 
Asa regwar system of managing 
fish ponds is pursued but by few, 
those who chuse to try the methods 
here recommended, will find them 
attended with pleasure and profit.
