answers when you have other work in hand cannot wait the 

 result of the infusion which has been put into the hole : if you 

 can, generally in a few minutes, if the insect is there, you will 

 observe a bubble in the mixture ; this is occasioned by the 

 insect moving, and shortly after it will be seen crawling up to 

 the top, presenting a thick horny head : then, with a long pin, 

 or thorn, gently run it slanting through the neck and give the 

 insect a sharp twist out. They are sometimes two or three inches 

 long, and very destructive, as they attack every fruit- bearing 

 tree, as well as others. When insects infest the leaves of trees, 

 they must either be picked off, or destroyed by smoking the tree. 

 Sulphur thrown on burning charcoal is very effective method of 

 destroying insects ; the fumes must be allowed to pass over the 

 branches. A pound of sulphur will suffice for very many trees. 



COLOUR OF FLOWERS. The colour, smell, and nutritive quali- 

 ties of plants, depend for their production chiefly on the action 

 of light. The propensity of plants to turn to the light depends 

 solely on the hardening and stiffening of one side, whilst the 

 other remains soft and pliable ; the side exposed to the light has 

 its moisture carried off by evaporation, and is rendered more 

 firm, contracted, and shorter, than the one less exposed. 



COMPOSTS Are mixtures of several earths, or dungs, for the 

 improvement of the general soil under culture, or for the culture 

 of particular plants. In respect of composts for the amendment 

 of the general soil of the garden, the quality must depend upon 

 the natural soil ; if this be light, loose, or sandy, it may be 

 assisted by the addition of heavy loam, clays, &c., from ponds, 

 tanks, and ditches. On the other hand, heavy clays and stub- 

 born soils may be assisted by light composts of sandy earth, all 

 kinds of ashes, rotten bark, saw-dust, and other similar opening 

 materials that can be procured. 



COMPOSITION FOR WOUNDS IN TREES. The following com- 

 position, prepared after the recipe of Mr. Forsyth, has been found 

 to answer extremely well : old fruit trees, such as the mango, 

 frequently derive benefit by having the composition applied, 

 after removing the cankered and decayed parts. It may also be
