When complete wood is laid crosswise in the bottom, on it are 

 tlirown tlie chunks of lime rock, then coal or wood, then a layer of 

 the lime rock or shells, then fuel enough to cover, and so on in alter- 

 nate layers. The top must be protected from the rain. Twenty- 

 four hours is enough for burning out the first kiln ; the powdered 

 lime is removed by opening a slide or door at the bottom. All is 

 not removed, but the empty space above filled with fuel and unburnt 

 lime as before. ]N"o w-ritten directions can be given that will supply 

 the need of an experienced man ; for one lime burner will use a 

 third less fuel than another and do as much work. Lime rock difi'ers 

 a good deal in toughness, so that no precise directions will suit all 



cases.

Grasshoppers. 

 Mr. W. W. Rumford, Tule, Tulare county, Cal.— I have discovered 

 a remedy against the gi'asshopper that so far seems perfect for the 

 protection of trees. Train them up four or five feet from the ground, 

 then put a disk of smooth tin, funnel shaped, just beneath the lowest 

 branch, large and downward. If the bark of the trunk is tender 

 protect with matting. The grasshopper does not jump high, but 

 -crawls up tlie tree or stalk of a plant. In this way they will go to 

 the top of ii telegraph pole. I also have some small trees protected 

 by gauze netting. They rarely injure early sown grain, as it is to 

 ioo near ripe before their advent. I have three trees with heads only 

 twenty inches from the ground, protected by the tin discs, and so 

 far they are safe, although the ground around is alive with the 

 passing horde. I have sat by the hour to see them climb up to the 

 tin, and then climb down again. 



The Xew Textile Rajoe 



Mr. W. F. Kcman, Clinton La., sent a piece of ramie plant, and 

 wished to repeat Bulwer's question. What will he do wnth it ? 

 In his vicinity, he says, it grows readily, and its cultivation requires 

 little labor. 



Mr. Solon Robinson.— The culture of this textile is being commenced 

 all over the south. Our correspondent's interrogation is an import- 

 ant one, and ought not to be carelessly answered.. I suggest that
