paper, or killed with formalin baits. Two tablespoonfuls of formaldehyde 

 (40 per cent) in a pint of equal parts of milk and water, set about the room 

 in plates, will attract the flies and kill many of them, provided there is no 

 other food or water for them to feed on. A piece of bread placed in the 

 middle of each plate for the flies to alight on will make the bait more at- 

 tractive. A constant warfare should be maintained against house flies.

the luna moth 

 Anna Botsford Comstock 

 Every year the entomologists at Cornell receive several luna moths 

 through the mails, and the senders always believe that this wonderful 

 creature was never before discovered. When one looks at this exquisite 

 moth he does not wonder that it is thus regarded. The first time the 

 writer saw a luna was in her childhood, when she fotmd one hanging, 

 wings down, from a shrub in the forest mantle, and she cried "What a 

 beautiful leaf! " But as she started to pluck it she discovered that it was a 

 great green moth. The luna is the moth of one of the four native American 

 silkwonns; the three others are the cecropia, the promethea, and the 

 polyphemus. Of them all the luna is the most beautiful. It may often 

 be seen flying around electric lights during May and June, and has been 

 likened to a great white ghost of a bird, appearing for a moment and then 

 vanishing in the darlcness.
