be given, which should be repeated every fortnight up to the end of 

 August, provided that it is not done naturally by rain. 



The wood that is cut from the vine, when pruning, can be used for 

 propagating young plants. To propagate the young plants, take the canes 

 which have been cut off, select all the wood which is not thinner than 

 one's little finger and cut this up into lengths, as suown in figure 4. 



This will give cuttings of two joints, as figure 5, but elose to the 

 buds and quite smoothly at both top and bottom of the cutting. In- 

 sert these, the right way up into a prepared bed, placing them three 

 inches apart with two-thirds of their length under ground, — one eye 

 will thus be under the ground and one above, as in figure 6 



As soon as the cuttings have made a growth of four or five inches in 

 length, they should be lifted and potted, or planted into their perma- 

 uent positions and treated in the way advised for the young plants sent 

 out from Hope Gardeus last year.

THEIR STRUCTURE AND LIFE HISTORY*

Perhaps one of the most marked faunal characteristics of the tropics

 during the day we remark the brightly coloured butterflies, the varied 

 forms of the beetles, the wonderful activities of the ants and termites,

 dusk, the large and small moths which flutter round our lights, the

 or, still more, experience the tormenting mosquito, or on the trees in 

 our gardens remark the prevalence of strange looking scales and large 

 and gorgeously coloured caterpillars, do we realize the importance of 

 the group here, compared with temperate parts. The constant dweller
