TREATMENT OF THE ALO'YSIA CITRIOD'ORA. 
BY A SUBSCRIBER. 
If your correspondent is not tired out with the many answers to his 
queries, respecting the best means of preserving the Verbena or Le¬ 
mon-plant from frost, I can hear testimony to its hardiness; when I 
resided at Oxford, we had two very beautiful plants, fully twelve feet 
high, and proportionahly stout in the stem, on either side of the par¬ 
lour window; the only defence they received was from a covering of 
hay and close matting, till about April, when the gardener removed 
the weakly shoots of the former year, and new wood was thrown out 
in abundance, inviting every passer-by to pluck a shoot, the fra¬ 
grance thrown into the room was delightful.

ARTICLE XIV.—ON THE MANAGEMENT OF PLANTATIONS. 
BY AN ARBORIST. 
In managing plantations, the object is to give at the same time a 
due proportion of shelter and air.—In many cases, plantations which 
have been well attended to, in respect of inclosing, draining, and 
properly planting, have thriven well for the first twelve or fifteen 
years; yet in fifteen years more, the forest trees have been ruined 
by allowing the scotch fir and larch, which had been judiciously 
planted for shelter, to remain for twenty-five or thirty years. The 
oak, ash, and sycamore have been partly destroyed, and what re¬ 
mains, is, for want of air, so drawn up, and left in such a debilitated 
state* that, though their oppressors he at length removed, they can¬ 
not support themselves, and the few that can stand, from the sudden 
transition which they have undergone, immediately stagnate, and 
become overgrown with moss. 
Too great a partiality for trees, often occasions an error, which 
defeats the object of the planter and improver. It is as necessary to 
thin and prune trees every year, as to plant them with core and
