THE NORMAL AND ABNORMAL SEEDLINGS OF THE MANGO. In connexion with the article on ' The production of more than one Seedling from a Single Seed of the Orange and Maugo', published in the current volume of the Afjr-iculturul Neivs on p. , the following remarks may be of interest. In the article referred to it was shown that the abnormal seedlings were of the nature of vegetative buds formed from the nucellus of the seed, and conse- quently, would breed true to the parent plant, while the normal seedling was the product of cross-fertiliza- tion and could not therefore be expected to come true. ilr. Jones, Curator of the Botanic Station, Doniiniea, Las furnished the following interesting information in con- nexion with this point. He says : — ' I have raised a large number of mango .«eedlings for stocks at various times, and I have noticed that the majority of varieties in Dominica are normal. Occasionally adventi- tious seedlings are formed. ' One point in connexion with this is wnith noting. When several seedlings are produced from one seed, one seedling, evidently the normal one, is stronger than the rest. It has twice the size and much greater vigour than the others, which are probably adventitious. Should this prove correct, it means that the adventitious which may probaljly breed true, can be selected ^vhen in the seed beds. This would be very important. It also explains why there is hardly a case on record where good varieties, which produce both normal and adventitious embryos, breed true ; for it is certain that the weak seedlings, probably adventi- tious, are discarded for the strong seedlings, probably normab. This point should be tested by growing the weak seed- lings ol such varieties until they bear fruit, when it can be seen whether they have come true to the origina
