 worms, white-ants, crickets and grasshoppers. They come out 

 of their holes and hop away as soon as a field is thoroughly 

 irrigated.

 of fowls (scratchers) in ploughed up fields before sowing; are 

 also good preventives. 



1.170. Against rats, the Scientific American recommends 

 the following remedies: 



(1) When a house is infested with rats which refuse to be 

 caught by cheese and other baits, a few drops of the highly 

 scented oil of rhodium poured on the bottom of the cage will 

 be an attraction which they cannot refuse. 



(2) Place on the floor, near where their holes are sup- 

 posed to be, a thin layer of moist caustic potash. When the 

 rats travel on this, it will cause their feet to become sore, 

 which they lick, and their tongues become likewise sore. The 

 consequence is that they shun the locality, and seem to inform 

 all the neighbouring rats about it, and the result is that they 

 soon abandon a house that has this preventive. 



(3) Cut some corks as thin as wafers, and fry, roast or 

 stew them in grease and place the same in their track ; or a 

 dried sponge fried or dipped in molasses or honey, with a 

 small quantity of bird lime or oil of rhodium, which will 

 fasten to^their feet and cause them to depart. 



(4) If a live rat be caught and smeared over with tar or 

 train-oil and afterwards allowed to escape in the holes of other 

 rats, he will soon cause all to take their departure. 



(5) If a rat be caught and a small bell be fastened around 

 his neck, and allowed to escape, all of his brother rats as well 

 as himself will very soon go to some other neighbour's 

 house. 



(6) Take a pan, about twelve inches deep, and half fill it
