should be cut from the seedlings and from the branch, so that the inner bark of 

 both can be made to touch accurately ; the two wounded surfaces are bound securely 

 with tape or bast fiber, and grafting clay applied to keep out air. The juncture 

 of branch and seedling should extend for a length of about 3 inches, but at no 

 point should the wound in either be deep ; the slices should in fact be of almost 

 uniform thickness throughout and not thick. Tenacious clay should not be used 

 to cover the inarch, it soon cracks and admits air. One part of fresh cattle dung, 

 mixed with two parts good soil, kneaded together with a little water, serves the 

 purpose excellently. Inarching can be done in India at any season, but it is most 

 successful when the trees are in active growth. It takes some time (several 

 months) before the inarched juncture is perfectly joined by the new wood and 

 bark cells. Meantime the seedlings in the pots must be carefully and regularly 

 watered. When the juncture is complete the leading shoot of the seedling should 

 be removed immediately above the inarch juncture and some days afterwards 

 the branch of the tree may be severed immediately below the juncture. 



"Trees for inarching should be in a sheltered situation, because if swayed 

 much by the wind the pots or the platform are disturbed from their position. 



"In planting out young grafts the pots should be broken if the young plant 

 can not be removed without disturbing the earth on the roots. If the earth on 

 the roots is much disturbed the plant will almost certainly die. They should be 

 planted with plenty of manure in pits three feet deep and wide." — [From "The 

 Mango in Porto Rico," by G. N. Collins, (Bulletin No. 28, Bureau of Plant 

 Industry), p. 15] 



Patch Budding: It would be almost impossible to propagate mango trees 

 in sufficient quantities for large commercial plantings by the method of inarching 

 as described above. With the recent development of interest in the extension of 

 the mango industry, several methods of budding, which permit of the propagation 

 of trees in commercial quantities, have been developed. And while these doubtless 

 require considerable more skill and experience on the part of the operator than 

 inarching, when the production of trees in quantity is desired, one of them will 

 have to be resorted to. The first method of budding successfully practiced was 

 that of patch budding, Mr. G. W. Oliver of the Department of Agriculture being 

 the first one to succeed with it in this country. The method as practiced by him 

 is described as follows: ["The Propagation of the Mango," by G. W. Oliver, in 

 the Florists Exchange, New York, April 19, 1902, p. 461.] 



"The method I wish to call attention to must be performed under certain 

 conditions, the first and foremost of which is that the stock must be in active 

 growth. The best time is when the new leaves are not far enough developed to 

 show the bright green color. The bark is then most easily removed. Choose the 

 thick part of the stem only a few inches above the surface of the ground ; cut 

 out a rectangular piece of bark about one and one-half inches in length, and from 

 the variety to be propagated cut a similar piece with a bud in the center, not, 

 however, from new wood, but from that which is at least two years old and which 

 has lost its green color and assumed the grayish brown tint. Fit the section 

 of bark, with bud attached, into the space formed by the removal of the bark from
