pollen from the stamens in the same, or 

 some nearly-allied flower, has reached 

 and impregnated its pistils. In favour- 

 able seasons, when genial warmth and 

 gentle winds prevail, impregnation is 

 readily effected by the plant's own provi- 

 sion. The pollen is never shed from the 

 anther of the stamen until the stigma of 

 the pistil is fully developed, and this 

 soon withers after the contact. 



Insects aid in effecting this impregna- 

 tion, and in frames, hothouses, &c., from 

 whence they are almost totally excluded, 

 other artificial means might be adopted 

 "with success to render flowers fertile that 

 had hitherto failed in producing seed. 

 Thus the gardener always finds the ad- 

 vantage of using the camel-hair pencil to 

 apply pollen to the stigmas of his forced 

 melons, cherries, and peaches. See HY- 

 BRIDIZING. 



INARCHING, or Grafting by approach, 

 differs from grafting only in having the 

 scion still attached to its parent stem 

 whilst the process of union with the stock 

 is proceeding. It is the most certain 

 mode of multiplying an individual that 

 roots or grafts with difficulty, but is at- 

 tended with the inconvenience that both 

 the stock and the parent of the scion 

 must be neighbours. 



Having the stocks properly placed, 

 make the most convenient branches ap- 

 proach the stock, and mark in the body 

 of the branches the parts where they 

 will most easily join to the stock, and in 

 those parts of each branch, pare away 

 the bark and part of the wood two or 

 three inches in length, and in the same 

 manner pare the stock in the proper 

 place for the junction of the graft ; then 

 make a slit upward in the branch so 

 as to form a sort of tongue, and make a 

 slit downward in the stock to admit it ; 

 let the parts be then joined, slipping the 

 tongue of the graft into the slit of the 

 stock, making the whole join in an exact 

 manner, and tie them closely together 

 with bass, and afterwards cover the whole 

 with a due quantity of clay, or wax. 

 After this let a stout stake be fixed for 

 the support of each graft, and so fas- 

 tened as to prevent its being disjoined 

 from the stock by the wind. 



The operation being performed in 

 spring, let the grafts remain in that posi- 

 tion about four months, when they will 

 "be united, and they may then be sepa- 

 rated from the mother-tree. In doing j 



his be careful to perform it with a steady 

 land, so as not to loosen or break out 

 the graft, sloping it off downwards close 

 to the stock ; and the head of the stock 

 cu' J.own close to the graft, and all the 

 old clay and bandage cleared away and 

 replaced with new, to remain a few weeks 

 ionger. Observe, however, that if the 

 grafts are not firmly united with the 

 stock, let them remain another year till 

 autumn, before you separate the grafts 

 from the parent tree. Instead of ap- 

 proach-grafting in the usual manner, it 

 is sometimes convenient to detach shoots 

 of the kinds to be propagated from the 

 plants on which they grew, and inarch 

 them upon the single plant, leaving a 

 piece at the bottom of each shoot suffi- 

 ciently long to thrust into a phial, which 

 must be kept constantly supplied with 

 water.
