HOW TO GROW GOOD COEN. 203 



7. The moth that visits granaries (Tinia granella) 

 may here be adverted to. The presence of the larvae 

 of the little grain moth may soon be ascertained in 

 the granary, when one finds several grains of corn 

 united by a web, to which will be attached bunches 

 of small granules, which are the exuviae of the 

 one or two caterpillars belonging to each group of 

 corns. 



The best method of preventing this is thorough 

 cleanliness, light, and ventilation in the granary. If, 

 however, the moth has got possession, then we recom- 

 mend sulphur to be burnt in iron pans — old saucepan 

 lids are as good as anything — stopping up all the cre- 

 vices. This will be an effectual remedy, not only for 

 the moth, but for the weevils and other insect pests ; 

 and if a pound of sulphur be occasionally burnt in 

 the barn, even rats must succumb to the gas which 

 is generated. 



8. The Meal-worm Beetle {Tenebrio nwlitor), which 

 generates commonly in the meal-bins of this country, 

 and the T. obscurus, which has been introduced in 

 American flour, are two forms of beetle, the larvae of 

 which are "meal-worms." These are best prevented 

 by not keeping too large a store of flour, always 

 having this dry and in the best condition, and storing, 

 as far as possible, in a clean, light, and airy position. 

 Indeed, as Curtis remarks, •' Cleanliness is the best 

 guard against these insects;" and we cannot better 

 conclude this chapter than by further quoting the 

 following from this excellent author : — 



In looking back to the variety of insects that feed upon corn, and 

 the multitudes that are often congregated in one heap, there can be 

 no doubt that a very large portion must be occasionally ground up
