the month of November. Let them 

 grow as tliey like the first year, and cut 

 them down to the ground the second, 

 they will then spring up and require 

 no more future care, than occasional 

 trimming with the pruning knife or 

 shears so as to keep the hedge in 

 shape. When it gets naked at the 

 bottom, it must be again cut down." —

The Laurustinus, Phillyrea, Laurel, 

 Furze, &c., referred to in the foregoing 

 article, are not sufficiently hardy to re- 

 sist the winter of the middle states, and 

 some of them would, it is presumed, 

 scarcely withstand the sun of the South- 

 ern. For ornamental hedges it is safer to 

 rely on the red and white Cedar, Chinese 

 and American Arborvitas, Juniper, Ame- 

 rican Holly, Variegated Euonymus, 

 Hemlock Spruce, &c. For purposes 

 of protection the Madura or Osage 

 Orange is unquestionably the best, 

 wherever it can sustain the winter — 

 which it is able to do so far North as 

 New York. The Buck Thorn (Rham- 

 nus catharticus) has been highly recom- 

 mended, more especially for colder 

 climates. The English method of plant- 

 ing on an elevated bank with ditch on 

 one or both sides, is inapplicable to 

 this country, where excess of moisture is 

 seldom felt : in other respects the mode 

 of treatment detailed in the preceding 

 article may be pursued in this climate.

The following are good directions for 

 the culture of the Heliotrope : — 



" Prepare in August as many shallow 

 thirty-two sized pots as will be required, 

 by fdling them to the depth of an inch 

 and a half with broken crocks, upon 

 which a layer of the rough sifiings of 

 leaf mould should be laid ; the remain- 

 ing space should be tilled with a mix- 

 ture of finely sifted leaf mould and 

 silver sand, previously well incorporat- 

 ed, which when pressed down (irmly, 

 should be exactly level with the border 

 of the pots. 



" For cuttings, the tips of the young 

 shoots about three inches in length, 

 should be chosen, and these should be 

 taken off immediately below a joint or 

 the base of a leaf bud. 



"After removing two or three of the 

 lower leaves, plant the cuttings in the 

 pots prepared, about an inch and a half 

 deep, and two inches apart ; water them 

 well with a fine rose two or three times, 

 so that every part of the soil may be 

 thoroughly moistened, which may easi- 

 ly be known by the water percolating 

 tlirough the bottom of the pots. If this 

 is not attended to, and the surface soil 

 alone is penetrated by the water, cer- 

 tain failure will be the result. 



"The cuttings, when planted, should 

 be removed to a cucumber or other 

 frame, where a tolerably damp heat 

 can be supplied ; they should be kept 

 shaded from the sun, and air admitted 

 in small quantities, only during the hot- 

 test part of the day. In about a fort- 

 night, the plants will begin to form 

 roots, and the shading may be gradually 

 diminished during the morning and af- 

 ternoon ; the quantity of air given them 

 may be increased by degrees, and at 

 the end of a month from the time ot 

 planting, the cuttings will be ready for 

 potting off singly.
