The Hawaiian forester and agriculturist . revent its accumulation. I refer to the fungusscientifically known as Thielaviopsis efJiaccficus, Went.

The earlierstages are not accompanied by the black color: on the con-trarv, the fungus merely softens the tissues, discoloring them butlittle. 125 I have described this disease as it relates to cane in a bulle-tin published by the Hawaiian Sugar Planters following is quoted from that source. After reading Itthe reader will see that this rot is one of ecjual interest to bothindustries. ** THE PINEAPPLE DISEASE.(Thiclaziopsis ct/iaccticits. Went.) The disease was first studied by Dr. F. Went, in Java. Hefirst investigated and classified the fungus causing the that time (1893) it has been observed in the West In-dies and in Fig. 1. Two cuttings to show more clearly the destractive action of the pine-apple fungus. The right hand untreated cutting has been completely ruined in afew days although its condition when pi*r>*ed was like that of the sample shownat the left. 126 It is coniinonly asserted that this disease of the sugar-canereceives its common name on account of the fact that its pres-ence in the tissues of the cane gives rise to an odor resembhng thatof pineapple. The specific name of the fungus, ethaceticus, refersto the same fact, its translation into English reading, aceticether, so that we may call the species the acetic-ether-producingfungus. It is true, that, in some of its stages, and especially in somevarieties of cane, the growth of the fungus gives rise to an odorreminiscent of ripe pineapple, but a delicate nostril would sel-dom, I think, mistake one odor for the other. More often theodor is that whicii we associate with fermenting fruit juic
