The Curator of the Botanic Station at Dominica recently forwarded to the Imperial Commissioner of Agri- culture some scale-infested twigs of lime trees from an estate in that island. Eroni the correspondence accompanying the .specimens it appears that a greyish fungoid growth on the lime plants is supposed to have caused the death of a number of the plants. Examination of the specimens sliows that the fungus referred to occurs only in connexion with the orange mussel scale {^fi/filaspis cifricola), and is probably parasitic on the scale insects, and not on the lime trees. The cause of the death of the plants, then, would not be the fungus, but the .scale insects, or some other cause which has been overlooked. In the Agricultural Nevs (Vol. II, p. 232) reference is made to two kinds of fungi found in Dominica on .scale insects. One of these is probably the same as the one under discussion, although it has not been identified. The other is reddish in colour and has been identified as Sphaeroitilbe voccojihtla. The estate on which these plants were growing is situated at an altitude of about 1,000 feet, in a district where the rainfall is about 200 inches per annum. The land has been recently cleared and there is a large amount of decaying vegetable matter on the surface or in the soil. The lime plants are young, and it is likely that these conditions and the scale insects present are together responsible for the death of a few trees, while the fungus is present as an enemy to the scales and not injurious to the plants. cost of the materials added, which is very small. Samples treated in this manner were sent out to India by the above syndicate, whose offices are in Temple Bar House, , and satisfactory reports regarding the same have recently been received.
