Black Rot.—Black rot is a disease of oranges that is not common in the gulf-coast states but is common in certain parts of California where navel oranges are grown. The disease is due to a fungus that enters through the navel end of the fruit. Fig. 8 while it is developing. Howe\'er, the disease has been observed in Florida on varieties of fruit other than navels, and seems to have found entrance to the fruit through slight defects at the blossom end. The disease will cause small green fruit to exude a drop of gum at the navel or blossom end of the fruit, to turn yellowish, and drop off. The rot is most often noticed just before healthy fruit colors. The fruit infected at this time turns a deep orange color and has the appearance of ripening prematurely. If this diseased fruit is cut open it will be found to have a black decayed center, principally along the core. This decay does not cause the fruit to soften so rapidly as some of the rots. In Fig. 9 is shown a fruit infected with black rot. The disease does not usually attract enough attention to call for remedial measures. Only a small percentage of the fruit is attacked. It would seem to be a wise measure to destroy the dropped affected fruit. 14. Maldigoina.—Throughout Florida and the gulf-coast states maldigoma, or foot rot, is a disease that is very common, especially on old seedling trees. The symptoms of the disease are abundant exudations of girni on the trunk of the tree near the surface of the grotmd. Close examination will show that the bark has been killed about the point of in- fection. The inner bark and finally t
