apart (it will require about 94- plants for the first tier). 

 Again, place another course of stones of the same size, bevel- 

 ing inwards on all sides at angle of 45° {fg. 9 1.) ; this fill with 



the same compost, and plant as for the first row of plants. 

 Proceed thus, stratum super stratum, until you have raised 

 your bed about 3 ft. high, which will give you six rows of 

 plants around your bed and one row at the top. The advan- 

 tages of this bed are as follows : — A much larger quantity of 

 plants is grown on a given quantity of ground. You obtaia 

 a succession crop, by placing your bed north and south. You 

 can water them with facility from the top, in which a trench 

 should be left for that purpose. The fruit can be gathered 

 with more ease and convenience, and the last and most 

 important advantage which I shall name, is, that your fruit 

 is free from sand and earth ; should heavy rains occur during 

 the period of its ripening.

PS. — To renew the bed : — In August, remove all the 

 stones but the lower row, and gently fork up the earth adding 

 a little rotten dung, and replant and replace as directed above.

Sir,

 by T. C. of Kensington (p. 332.), for the destruction of wasps, I 

 beg leave to send you an account of the method practised by 

 me for many years, which, I am convinced, is as simple and 

 effectual as any that can be adopted. 



I give a small reward to my men for every wasp they bring 

 to me from the beginning of March, up to the second week of 

 June; from June I give a reward as above for every nest
