SALMONIA. 



HAL. The fly you see is called by fisher- 

 men the alder fly, and is generally in large 

 quantities before the May fly. Imitations 

 of this fly, and of the green and the grey 

 drake of different shades, are the only ones 

 you will need this morning, though I doubt 

 if the last can be much used, as the grey 

 drake is not yet on the water in any quantity. 



PHYS. Pray can you give us any account 

 of these curious little animals ? 



HAL. We ought to draw upon your 

 stores of science for information on these 

 subjects. 



PHYS. I really know nothing of Entomo- 

 logy, but I am desirous of acquiring know- 

 ledge. 



HAL. I have made few observations on 

 flies as a philosophical naturalist. What I 

 know I will state, but at another time. But 

 see, the green drake is descending upon the 

 water, and some are leaving the alders to 

 sport in the sunshine, and to enjoy the plea- 

 sures of their brilliant, though short exist- 

 ence; and their life, naturally ephemeral, is 

 made one of scarcely a moment, by the fishes
