The mango tree is not well established in Guam. There are few trees on the 
island, but these produce fruit of the finest quality. Guam mangoes are large, sweet, 
fleshy, juicy, and almost entirely free from the fiber and the flavor which so often 
characterize the fruit. The trees grow to great size and appear to be thrifty; but 
nearly all onthe island haye been blown down by baguios, or hurricanes, and con- 
tinue to grow, as it were, resting on their elbows. The cause for this, I think, is the 
shallowness of the soil, the hard coral rock not allowing the roots to penetrate to 
any great depth. ‘Those which remain standing are in low, protected places, where 
the soil is comparatively deep. The natives value the fruit more highly than any 
other food product of the island, Indeed, the presence of a mango tree on a rancho 
enhances its value. During some seasons no fruit is produced. The natives fre- 
quently cut gashes in the trunk and build fires beneath the limbs, thinking that the 
tree will be induced thereby to produce a good crop. Frequently one portion of the 
tree will bloom or send out fresh foliage, which is reddish and tender when new, 
while the rest of the tree remains dormant, and it often happens that the fruit is 
perfectly ripe on certain limbs, while on others it is still green. The trees are prop- 
agated by seed, and the fruit of the seedlings appears, in Guam, to be identical with 
that of the parent tree. The seeds must be planted when quite fresh. The young 
plants are tender, and are killed in transplanting if the root be injured. Grafting and 
inarching is not practiced, though it could be done with good advantage from limbs 
of mature trees producing especially fine fruit,” and it could be carried on with espe- 
cial facility with the prostrated trees, which still continue to grow vigorously and 
bear fine fruit. The tree is in Guam entirely free from disease or injurious parasites. 
In view of the excellent quality of its fruit and the danger of bringing diseases and 
parasitic insects with specimens from abroad, importation of living mango plants 
should be forbidden. The failure to produce crops each year is probably owing to 
the fact that the dry season in Guam is not sufficiently marked to cause the trees to 
a Grafting should not be performed during the rainy season nor in the midst of 
the hottest part of the year. Inarching of the herbaceous parts is most successful.
