product of the pyroligneous acid makers, and known on the 

 Continent by the name of pyroxylic spirit). The expense 

 of this is trifling: ]£ oz. of Indian rubber and 1^ pint of 

 the ether will saturate 10 lbs. of twine. The twine need 

 never be varnished again, and will last many seasons ; is per- 

 fectly impervious to wet, and is not affected by hygrometric 

 changes in the atmosphere ; so that, when once strained tight 

 by the stakes at b, it will remain so. 



I have these stakes in use, and they answer admirably, and 

 look exceedingly neat. I should think, about London, where 

 pea stakes are so dear, this would be the cheapest plan mar- 

 ket-gardeners, &c, could adopt. Occasionally, in very long 

 ranges, a stay or two in the length may be placed as shown 

 at c c. It is obvious that these stakes are applicable also to 

 clumps or baskets, but the cord should then be arranged 

 spirally through the holes. They are much stronger than 

 the wire things generally used, and may be varied to any size 

 or shape.
