tain laurel, thornapple, orangewood, torchwood, mastic and yellow buckeye have some of 

 the characteristics of boxwood and might be used for less exacting purposes. — Chas. H. Otis.

 1919: 103-104. 1919. — This is a further account of the brimstone tree, a name applied to 

 species of Morinda, family Rubiaceae and to Mitragyne stipulosa Kuntze [Mitragyne macro- 

 phylla Hiern.] — E. M. Wilcox. 



1991. Anonymous. Le service forestier de l'Annee d'Orient. [The forest service of the 

 Army of the Orient.] Rev. Eaux et For6ts 57: 196-199. 1919. — In January, 1918, a forest serv- 

 ice was formally established in the French Army of the Orient. This service was charged 

 with the duty both of supplying the French army with wood and of apportioning the forests and 

 wooded regions in the zone of the rear among the various allied armies. In spite of the many 

 difficulties encountered, it succeeded in meeting all of the needs of the army for wood, saved 

 tonnage, stabilized prices, and preserved many forests from destruction. — S. T. Dana. 



1992. Anonymous. Tabanuco gum or Porto Rican elemi. Sci. Amer. Suppl. 87: 201. 

 1919. — The plant yielding the Porto Rican elemi is known botanically as Dacryodes hexandra. 

 The tree is abundant on the island of Porto Rico and attains large size. The bark contains 

 great quantities of gum, locally known as tabanuco. It is used for incense and in torch 

 making. It is thought that a good use can be made of it in the manufacture of varnishes, soaps, 

 felting and printers' ink. — Chas. H. Otis. 



1993. Anonymous. The grass tree resins of Australia. Sci. Amer. Suppl. 87: 137. 1919. 

 — Fourteen species of Xanthorrhoea or "grass tree" occur in Australia. The resins collected 

 from these trees may be made to yield picric acid, in amounts varying from 50 per cent in 

 the case of X. hastilis to 5 per cent in resin from X. arborea. The resins are used in the prep- 

 aration of spirit lacquers, varnishes, sealing wax, and for similar purposes. — Chas. H. Otis.

1996. Aubert, L.-G. L'o'idium et les chenes de l'Ouest de la France. [Oldium and the 

 oaks of western France.] Rev. Eaux et For6ts 57: 189-195. 1919. — The fears which were ex- 

 pressed by M. Doe" in Rev. Eaux et For6ts, March, 1919, as a result of his experiences in Cham- 

 pagne, that the oidium disease may prove fatal to the oak in France, are not substantiated 

 by the history of the fungus in the western part of the country. Here, in spite of the fact 

 that the disease has been present and at times virulent since 1907, no serious damage has been 

 done and no particular difficulty has been experienced in converting coppice stands into high 

 forest. The explanation of the markedly different reaction of the oak to the fungus in the 

 two regions appears to be that in Normandy and Brittany the oak is in the zone of optimum 

 growth, while in the more continental climate of Champagne its physiological resistance is 

 less. Even in western France, however, individual trees suffer seriously from the disease 

 when their vitality has been weakened by frequent pollarding or other mistreatment. — *S. T. 

 Dana.

1998. Bell, T. R. D., and others. Administration report of the forest circles in the 

 Bombay Presidency (including Sind), 1917-18. 178 p. Bombay, 1919. — At the close of the year 

 the area of reserved forests was 13,942 square miles, and 7728 square miles were under approved 

 working plans. Tarwad (Cassia auriculata) was, under pressure to develop tanning mate- 

 rials for leather required for war purposes, taken up for its bark and efforts make to increase 

 its natural supply. Many tons of seed were collected in the Northern Circle and sown, and
