SALMONID.E. 



to drag for Salmon ; and it must have been difficult to 

 preserve the balance in such frail and fragile machines. 

 The net was attached to the two boats, and connected 

 them. When all was clear, the fishermen made with their 

 paddles a considerable circle, and then reunited, drawing 

 in cautiously the sweep. They seemed very dexterous in 

 the management of their canoes, and perfectly unconscious 

 of danger. The first essay was a failure ; a Salmon of 

 ten or twelve pounds 1 weight leaped over the corks." Long 

 doubly-walled trammel-nets are now in use near Shrewsbury. 



The length of the head of the Salmon, as compared to the 

 whole length of the fish, is as one to five : the eye rather small, 

 placed nearer to the point of the nose than to the posterior 

 edge of the gill-cover : the peculiarities of the teeth and the 

 parts of the operculum have been already described ; the origin 

 of the last ray of the dorsal fin about half-way between the 

 point of the nose and the end of the tail ; the first two rays 

 simple and shorter than the third, which is the longest and 

 branched ; all the other rays of this fin branched ; the last 

 ray double, but arising from a single origin, is only counted 

 as one : the posterior edge of the base of the adipose fin is 

 half-way between the origin of the last dorsal fin-ray and the 

 end of the tail, and over the origin of the last ray of the anal 

 fin. The pectoral fin two-thirds of the length of the head ; 

 ventral fin in a vertical line under the middle of the dorsal 

 fin, with an axillary scale two-fifths of the length of the 

 ventral fin itself; the anal fin commences about half-way 

 between the origin of the ventral fin and the commencement 

 of the lower caudal fin-rays, the third ray the longest, the first 

 two rays simple, the others branched : the form of the tail 

 has been already noticed. The body is elongated ; the 

 dorsal and abdominal line about equally convex ; the lateral 

 line near the middle of the body, dividing it equally ; the 

 fleshy portion of the tail slender, and ending in the form
