438 On the White-DUght, or American Bug. 
Propagatjon. — In the middle of March, take some of the yoiing 
shoots of your old plants off, at a joint, put them into pots filled with the 
above compost, and make them quite firm; give them a gentle watering, 
and place them in a strong hot-bed. 
Cultivation. — After your cuttings have taken root, and begin to 
grow, bring them into the hot-house for a few days, to harden their 
wood, and then pot them off singly, always using the above compost; 
give them a good watering, and replace them in the back of your frame, 
shading them for the first week. If the sun is powerful, let them re- 
main there till they have grown nearly to the glass, when they must be 
taken back to the hot-house, and be grown as fast as possible, giving 
at all times, plentiful supplies of water. They must be re-potted in 
the months of April, May, July, and September, or else they will 1)6 
stunted in their growth. 
As the Salvia is frequently, nay always, attacked by the Red Spider, 
fAcarus,) and as this destructive insect disfigures the plants to a great 
degree, by causing the leaves to be spotted and discoloured, I would 
advise them to be well syringed four times a week, after thtir being 
re-taken to the hot-house. 
If any gardener were to follow the above method, he would find his 
endeavours crowned with success. 
I could furnish the Register with some more met'iods for cultivating 
other exotics, if they would be thought worthy of receiving.* 
The Conductors of the Register, or any of their numerous readers, 
would much improve the work by inserting plans of metallic hothouses, 
of houses worked by steam or hot water, and also of flower gardens and 
])leasure grounds. 
Wishing success to your undertaking, 
I remain. Gentlemen, 
Yours, &C.5
