BEHAVIOR OF SPIDERS AND OTHER INSECTS 441 



ing manner: "A strong piece of iron wire, three feet, eight 

 inches long, is bent into a circle with one foot diameter — the 

 ends are then bent at right engles so as to lie adjacent and 

 parallel to each other. The ends are inserted into the small 

 end of a six inch ferule and soldered fast. A short two foot 

 handle will be found best for sweeping. The net consists of 

 white muslin — a conical bag about eighteen inches deep. The 

 tip is cut off where the circumference of the bag measures about 

 three inches and is replaced by a cloth bag four by six and a 

 half inches. This small bag is sewed to the point at which the 

 circumference of the large net is four inches, thus, leaving a 

 sleeve which hangs down into the small bag — this small bag 

 will just hold a quarter pound paper bag. The sleeve of the 

 large net fits into the paper bag. When filled from a minute's 

 sweeping, the paper bag is pinched at the opening, taken out 

 of the net and placed in a botanical can. Upon the return to 

 the laboratory the bag is opened at a well lighted window and 

 the contents picked over for specimens."
