acrid substances recommended in the chapter containing 

 4 Observations on Insects and the Diseases of Fruit Trees/ 

 page 13, are not only adapted to the destruction of insects, 

 but the use of them in this way, will produce an incalcula- 

 ble benefit to the land, and in many cases preclude the 

 necessity of using any other manure. 



The ingredients alluded to consist of ashes, charcoal dust, 

 plaster of Paris, tobacco dust, lime, salt, soot, pepper, pot- 

 ash, saltpetre, snuff, and sulphur. The proportions may be 

 as follows : Of the first four articles, half a bushel of each j 

 of the next three, a peck of each ; and of the last five, say 

 one pound of each ; which will make together three bushels 

 of compost. 



As all land possesses inorganic matter, which contains 

 more or less of the elements comprised in the above reme- 

 dies, and as some land contains more of one element than 

 another, a judicious choice may be made from the above 

 list, with a view to suit all the various kinds of soil ; thus, 

 in locations open to sea breezes, which replenish the earth 

 with salt', that article may be dispensed with, and another 

 substituted ; and on land which is not susceptible of being 

 improved by lime, perhaps the salt may be beneficial ; but 

 it is presumed that in most cases a compost made of all, or 

 as many of the different articles as are attainable, would 

 produce a lasting benefit to land in general, by sowing, say 

 at the rate of a bushel per acre, once a week, at those sea- 

 sons of the year when it will avail most in the destruction 

 of reptiles and insects; and as the primary object of using 

 the compost is to prevent our fruits from being destroyed, it 

 would prove most effectual if sown out of a wagon, from 

 which, in passing between the trees, the leaves could bo 

 dusted. See pages 19, 89 and 104, of the first part.
