Logwood Root-rot. By P. S. Bark (Journ. N. Y. Bot. (hud. vol. 

 iv. Jan. 1903). — This disease is prevalent in Jamaica, and is spreading. 

 It seems first to attack the small rootlets, spreading to the larger roots, 

 and to the crown, when the tree dies. It appears to he caused by the 

 mycelium of one of the Hymenomycetes. An examination of dying trees 

 shows the roots to be badly rotted. These surface tissues are invaded by 

 a white fungus mycelium that is usually more abundantly developed in 

 the space between the bark and the wood. 



It is recommended that dying trees should be dug out and the roots 

 burned as soon as the disease can be detected. Where it is confined to 

 small definite areas, it is advisable to dig a trench three feet deep just 

 outside the diseased area, in order to prevent its spreading underground 

 to the roots of healthy trees. Whatever the cause or the nature of the 

 fungus, leaving stumps of trees that have died from this disease in the 

 neighbourhood of living trees is clearly dangerous. — M. C. C.

Lumber Industry in the State of New York, A History of. 



By William F. Fox (U.S.A. Dep. A<jr. Jiur. For. Bull. M\ 1902).— No 

 more complete and interesting history of the lumber industry has been 

 got together than the present, and from the opening page onwards the 

 reader is fascinated with the pleasantly written account of what might well 

 be called the life-history of this vast and important industry. 



From the time when the pioneers first swung their axes in the 

 primeval forest of New York when the whole was a silent unbroken 

 wilderness, a primeval forest which in grandeur and undeveloped wealth 

 was unsurpassed in all the region of the Atlantic coast— down to the 

 present day, with its sawing and wood-pulp machinery, and vastly 

 increased volume of business, we have a very lucid account of the rise and 

 progress of this far-reaching industry. 



It would appear that about 1014 the first houses were built at Albany 

 and on Manhattan Island, the territory which now constitutes the State of 

 New York, and so rapidly has business developed that in 1880 the com- 

 bined lumber product of the 2,822 saw-mills was no less than 1,148,220,000 

 feet, which necessitated the employment of 17,509 men. 



New York was not originally a forest State, but essentially a white- 

 pine State, the trees ranging from 150 feet to 100 feet in height, with ft 

 diameter, at breast high, of from two feet to four feet. The numerous 

 beautifully executed illustrations of rafting in many of its stages, pit- 

 sawing, Ac., still further enhance the value of a most creditable account 

 of the history of the lumber industry. — A. J J. W. 



Lycoris Spreng:eri. By J. G. Baker [Gwrd. Chron. No. 685, p. 409, 

 fig. in Supplement; Dec. 27, 1902).— This is a new and distinct species 

 of this genus, with purplish-rose-coloured flowers, and said to be a native 

 of Japan. Its nearest relative is L. v/uaviujera, from which it differs 

 in several respects.™ Q. S. S.
