 and lined with cork at the top and bottom, and 

 made to fasten close. Camphor must always 

 be secured in the boxes to keep out mites,

 lidj which should be covered with wire gauze, 

 or coarse canvass, for the admission of air. One 

 end should have a hole and a cork fitted to it, 

 to put the caterpillars in. But a box made of 

 tin, perforated with minute holes, and having a 

 hole at one end, as above, is by far the best, as 

 the food does not wither so soon as in chip 

 boxes. Some of the plant on which the cater- 

 pillars are found, must be placed with them.

 having the side? covered with brass wire gauze
