The Salmon (bred both in the sea and in rivers) is 

 another fish winch comes in shoals at certain times; 

 but this is on another occasion. The female salmon 

 chiefly ejects her roe at the mouth of rivers, in shallow 

 "water ; the male COPJCS presently after, keeps other 

 fish from devouring it, and casts his sperm upon the 

 roe, They are in great plenty from the middle of 

 April till the middle of July, at which time also they 

 come in shoals into the rivers, partly to refresh them, 

 selves in fresh water, and partly to rub or wash off in 

 the strong currents, a greenish vermin called salmon 

 lice ; insects wisely designed by the Creator to drive 

 this rich and valuable fish into the hands of men* 



The salmon when they are going up the rivers out 

 of the sea, always swim as near the bottom as they 

 can ; and on the contrary, when they are going down 

 them into the sea, they always swim near the surface. 

 The reason is, in going up they swim against the cur- 

 rent, which always runs swiftest at the surface. When 

 they are going down on the surface^ the current aloiie 

 is sufficient to carry them-. 



At Leixlip, seven miles from Dublin, there is a 

 iine water. fall, or salmon. leap, so called from the 

 numberless salmon which leap up it, at the season of 

 the year for spawning. When they come to the foot 

 ojf the fall, you may ob erve them frequently to leap 

 up just above the water, as if to make an observation, 

 of the distance. Soon after they leap up again, with 

 an attempt to guin the top, and perhaps rise near it, 

 but the falling water drives them down again : the same 

 fish soon springs up again, and rises above the fall; 

 yet this is equally unsuccessful, for dropping with 

 their broadsides on the rapid curvature on the waters, 

 they are thrown back again headlong. The only 

 method of succeeding in their attempt is to dart their 

 heads into the water, in* its first curvature over the 

 rocks ; by this means they first make a lodgment on
