GRAFTING THE MANGO TREE. 



By Horace Knight. 



The object in grafting is to perpetuate any desirable fruit without 

 having recourse to seeds. Experiments have proved beyond a doubt 

 that sections of the mango tree will keep good for grafting purposes 

 from three to six months' time, according to variety and to the con- 

 stitution of the tree from which they are obtained. This gives us the 

 opportunity to import sections of the most desirable class of tree 

 from any part of the globe with a certainty of their growing when 

 properly prepared and tied on. 



After twelve years' close observation and a large number of ex- 

 periments (more or less useful) made on the mango tree, the conclusion 

 I have arrived at is, that no other tree is simpler to graft. The work 

 can be successfully done by any one and at any time, whether the sap 

 is active or dormant. The buds are certainly not so quick in coming 

 when the sap is down, but they make up for any delay when once 

 started. 



Still, it cannot be said that grafting, when the sap is down, is the 

 best time for the operation. On the contrary, the first three months 

 in the year have proved to be preferable. All the remarks in this 

 article apply to one process only — that is, the use of bark without any 

 wood adhering to it Up to date, the best material for tying on the 

 grafts is ordinary candle cotton, procurable at the ironmongers, and 

 generally sold in 1 lb. balls. The grafts are simple pieces of bark,
