A General Treatise of

River-water through it, there will be a constantSupply of Feeding-Matter brought in with theWater, which will be both grateful and nourish'ing to the Fish ; and especially, if your Canalbe so made, that the Fish in it are given tobreed ; but that should be always avoided,where we would have our Fish thrive and grow jlarge : And if we would prevent their breed-ing, it is necessary to let the Sides of the Canalbe cut downright, and fenc’d up with Plank, sothat there be not any Part of the Canal lessthan two Foot deep in Water at least ; for aWater of that depth will never hatch any Spawn •of Pond Fish : And then if We take this Care \of our Fish, rather to make them feed than in- 1crease, we must also provide some deep Places >in the Canal, of about six or seven Foot Water ; ,

for it is a certain Rule, that all Fist, in proper- !tion to their bigness, will chuse to lie in theshallowest or deepest Waters ; the very small inthe very shallow Places, and the very large inthe deep ; and without such Deeps, the verylarge will not thrive. ;

In a Pond of the bigness you mention, if theRiver was not to feed it, you might maintain 1about fourteen Brace of large Carps, and twiceas many Tench, to thrive well; but as the Pond iis fed by the River, you may well enough main-tain twenty one Brace of Carps, and forty twoBrace of Tench, and expect them to prosper, 1without giving them any extraordinary Feed ; •

but for the fake of the Pleasure it may be to jyou in viewing your Fist now and then, it ma/be proper enough to use them to feeding atsome certain Hour every Day, that you maytake them as you fee convenient ; they willsoon know you, and come at any Call you ust
