It should be remembered that the seedsdo not retain their germinating power more than one to twomonths after removal from the fruit. In many localities inthe Tropics seed is likely to be destroyed by the mango weevil,which enters the fruit when it is young and goes through itstransformations in the kernel of the seed. The flower panicles, the young fruit, and the growing twigsare often attacked by the fungous disease known as the mangoanthracnose. This causes a blighting of the twigs and flowersand prevents the setting of fruit. It is particularly prevalent. Fruiting Branch of Litchi FRUITS AND NUTS IIT in moist weather but it can be controlled by spraying withBordeaux mixture unless repeated and frequent rain stormsoccur during the flowering season. The fruit also fails to setif high winds and heavy rains occur during the flowering sea-son even without the attacks of anthracnose. If the settingof fruit should thus be prevented by these causes a new cropof flowers may be produced a month or two later, thus bring-ing a crop of fruit to maturity out of the regular season. Inthese respects the mango is like the avocado, which is alsoaffected by anthracnose in the same manner and which may beprevented from setting fruit by persistent rain during theflowering season. The mango has often been called the apple of the Tropicsand sometimes the king of fruits. The term apple of theTropics is more or less appropri
