along the margins of ponds^ rivers, and ditches ; 

 and also among the mud at the bottom, and the 

 contents carefully examined. It will also be 

 found very useful for brushing grass and 

 weeds in fields, ditches, on banks, &c. A 

 bag net made of green gauze, from two to three 

 feet long, and fitted to the same hoop, may be 

 made to serve various purposes. With it butter^ 

 flies, moths, and other insects on the wing may 

 be cauglit, and by giving it a twist the mouth 

 may be completely closed, so as to prevent 

 the escape of the captive. When fixed to a pole 

 twenty or thirty feet long, Mr. Haworth consi- 

 ders it the best net for taking the Purple Empe- 

 ror butterfly, (Apatura IrisJ whose residence is 

 generally on or near the tops of lofty oaks. It 

 will also be found preferable to the water net, 

 for pushing through grass, &c. as, from its 

 depth, flying insects cannot so readily escape. 

 If the hoop of the water net should be consi- 

 dered too small, a piece of cane bent to the size 

 required, and tied to the stick, will be a good 

 substitute.
