gordingly you judge whether the flock was too little or too 
much for the water. Thus, by the thicknefs or fatnefs of 
cattle, you judge if your ground will carry more or not; and 
both as to {pecies and number of fifh, experience muft be your 
guide in the flocking of waters. 
However, to fave lofs of time, which you muft fuftain by 
making your own experience, I will give the beft directions I'can, 
for the firft entry upon your bufinefs, and not leave the matter 
wholly in the dark. 
If the pond be fupplied with a aehite fat water upon great 
rains, you may put into it at firit three hundred carps per acre, 
in cafe there be three or four acres, elfe not fo many. And 
it will be expedient to put in forty or fifty tenches for a trial, 
becaufe this fort of water is moft proper for carp; but being 
laid dry, fometimes may prove well for tenches alfo, which, 
when thriven, are a very good fifth; but this proof by trial 
muft determine. 
You may add perches to any number, and not hurt the 
water: I propofe fix hundred; for though they are great 
breeders, being alfo fifhes of prey, they devour their own 
fpecies as much, if not more than any other; and by deftroy- 
ing‘the fry of bred fith, they preferve the food for the main- 
tenance of theirifeeders, which the fry would intercept; fo 
do good rather than harm. I took once out of a perch’s 
belly of ten inches, ten other perches. This is efteemed one 
of the beft forts of frefh-water fth, and therefore defervedly 
to be-encouraged.
