After a year or less of growth, wlien the bond is complete, the 

 graft is separated. 



[There are five forms of inarching treated on by M. Baltet, 

 some of which differ so slightly from each other that we con- 

 sider it not worth while to illustrate the whole. The first is 

 what he calls " in placagc,'' and consists in merely removiug a 

 slice of bark and wood from the stock and graft respectively, 

 and binding the naked surfaces close together by a ligature of 

 bast, cotton, or wool, and protecting it either with grafting 

 •clay or wax. The second is what he calls " en incrustation." 

 Two sloping cuts are made on the graft, so as to form an 

 angle, aud a corresponding angular cut is made into the stock 

 to receive the scion, which, when bound together as described 

 above, unites with the stock. The three following are so dis- 

 tinct we shall treat them separately.]

 — Fi;!. 1. Over and above the Ugature the graft can be made 

 ;stUl safer by making on the two naked surfaces where the bark 

 -has been removed a set of correspondiug tongues (a aud b). 



"which are united as in c. If a slow union is dreaded the stock 

 is headed-dowu at the time of inarching, aud the graft appUed 

 on the top. 



BuTiRESs-isARCHixG (Grcffage par approche en arc-houtant). 

 — Employed more especially for the restoration of plants, this 

 mode of inarching is equally useful for propagation, and is 

 practised from April till July. The chief difference between 

 "this and the preceding consists in heading-down the graft, tree, 

 ■or branch, and introducing it under the bark of the stock. 

 The graft being topped aud cut slantingly, thin at the tip 

 under the shoot or terminal branch, > 



at is inoculated on to the stock by 

 means of an incision — thus, X, 

 made in the bark. The position 

 of the incision is regulated ac- 

 •cording to the length of the graft, 

 but about three-quarters of an inch 

 lower, in such a manner that, to 

 introduce the graft it is slightly 

 bent from above downwards to 

 give it a returning motion ; then 

 slide it under the bark of the in- 

 cision as if it should act like a 

 buttress. The two principal modes 

 of buttress-inarching are only appU- 

 cable during spring and summer.

a terminal shoot, we cut the graft 



(s) in a flat slanting direction, 



aud introduce it imder the bark of the stock (x), where it has 



been raised (v).

 ai-ec rameau). — Fig. 3. The graft (l) bearing an adventitious 

 shoot wiU be shortened about three-quarters of an inch by a 

 flat sloping cut (n) on the opposite side from the shoot ; care 

 must be taken to reduce the thickness of the slant, except at 

 the point, and not to remove the leaves neither of the branch 



nor the graft. The stock is a distinct tree (o), bearing the 

 graft-branch. The incision (p) is made in such a way as that 

 the graft will be inserted as represented at R. The shoot (m) is 

 preserved entire, or shortened to two eyes, according to its

length. It is called an adventitious shoot if it is produced in 

 the current year on an herbaceous graft-branch ; then the graft- 

 ing should have been done in summer. It is called young 

 wood in the spring on the woody graft-branch, or the graft- 

 branch of the preceding year. In that case the gi-af ting should 

 have been performed from April to June. 



[Buttress-inarchiug is a safe and excellent mode of renewing 

 detects in trained trees where the symmetr3' ol the tree is an 

 object of consideration with the cultivator. It not uufrequeutly 

 happens that a tree of great beauty of form suffers by the loss 

 of a branch either by the vicissitudes of the season or by acci- 

 deut ; iu such cases it is most desirable that some remedy 

 should be available, aud there is no better method of repairing 

 such injuries than by this method of buttress-inarchiug.] —

SUCCESSIONS OF VEGETABLES.— Xo. 6. 



CAULIFLO'WERS. 



E.vRLY London. — A good early kind, with fine medium-sized 

 heads, not very close, but white and good. Sow August 20th, 

 February 1.5th, and March 6th in gentle heat ; on March 15th 

 under a south wall ; April 6th and 26th, and May 20th. 



Early Dwarf Mammoth, or Froqmore Forcing. — Sow Au- 

 gust 20th ; on Februarv 15th and March 15th iu gentle heat ; on 

 March 20th under a south wall ; -ipril 6th aud 26th, and May 20th. 



E.uiLY Dwarf Erfurt. — Plant dwarf aud compact ; heads 

 large, white, compact, and excellent. Sow August 20th ; March 

 lyth in gentle heat; March 20th on a south border; April 6th 

 and 26th, and May 20th. 



Walcheren. — Heads large, not very close, but white and good. 

 S.)W August 20th; March 15th in gentle heat; April 6th and 

 2uth, and May 20th. 



ST.ADTHOLDER. — Heads large, compact, and solid. Sow Au- 

 B^ist 20th, AprU 6th and 26th, and May 20th. 



Asiatic. — Very large close heads. Sow March 20th under a, 

 south wall ; April 6th aud 26th, and May 20th. 



Lenormasd's. — Large close heads. Sow March 20th under a 

 south wall ; April 6th aud 26th, and May 20th. 



Yeitch's Autumn Giant. — Heads large, compact, firm, and 

 ■hite ; distinct from all others, and a valuable acquisition. Sow 

 August 20th, April 6th and 26th, and May 20th. 



Here we have eight sorts, and all good. Four will be suffi- 

 cient for most gardens, and those which I consider best are 

 Karly London, Walcheren, Stadtholder, and Yeitch's Autumn 

 Giant, and Early Dwarf Mammoth (Frogmore Forcing), for 

 growing iu pots in cool houses, also under hand-glasses. The 

 most useful of aU is Walcheren ; by sowing it on August 20th, 

 September 7th, February loth, March 15th, iu gentle heat ; on 

 March 20th under a south wall ; and on .AprU 6th, May 20th, 

 and June 7th it affords a supply of good heads from the close of 

 May to the January foUowiug. Indeed I have now iu a south 

 border plants each with a head the size of the closed hand, and 

 these, if taken up, laid in a cooljilace, and protected from frost, 

 keep good a month or six weeks. I am also persuaded a like 

 result would be attained by frequent successional sowings o£ 

 Yeitch's Autumn Giant, a much superior variety ; but I have a
