162 THE NEW AKT OF BREEDING FISH. 



friend and countryman, Mr. Alexander Keiller ; ob- 

 servations which, I doubt not, will be interesting 

 even to the unscientific and general reader." The 

 observations were made on the river Save, a tribu- 

 tary of the Grotha, near Jonserud, where the water 

 is invariably clear. They were made from a move- 

 able observatory, lantern-shaped, suspended by 

 means of ropes and puUies from a pole fixed in the 

 bank and inclining over the river. This observatory 

 is large enough to . hold a man, and a drawing of it 

 represents Mr. Keiller seated in it, and observing 

 through its bottom the fish that swim or perform 

 other operations beneath him. You have seen a 

 bale of goods suspended from a crane over the hold 

 of a vessel. Imagine the bale a large glazed frame, 

 with a bottom strong enough to sustain the weight 

 of a man, the hold of the ship the bed of a river, 

 and Mr. Keiller sitting within the glazed frame, and 

 then you will have a notion of his ingenious obser- 

 vatory. 



Let us now see what he saw from his watch-box 

 hanging over and a little above the river. " Sal- 

 mon," he says, " are pretty abundant in the Save. 

 The fishing produced, including grilse, about three 

 thousand pounds weight annually. Many fish were 

 taken in weirs, others in nets, or by the rod. The 

 larger salmon always appear first in the spring ; as 

 the summer advances, the fish are much smaller ; 

 but in the autumn heavy fish again show them- 

 selves. These are not fresh run, however ; at least
