AMERICAN FORESTRY 



'T'HE Fungal Diseases of the Common 

 1 Larch, hy W. E. Hiley, 204 pages, pub- 

 lished by the Clarendon Press, Oxford, 1919. 

 This treatise attempts to discuss the dis- 

 eases of the European larch (Larix Euro- 

 pea) and their economic importance in 

 terms understandable by the layman, while 

 at the same time including thoroughly 

 scientific descriptions of the characteris- 

 tics and life history of the fungi described. 

 Nearly a quarter of the entire volume is 

 devoted to a discussion of the larch canker 

 (Dasyscypha calycina), which is described 

 as exceedingly common, very destructive, 

 and likely to become even more disastrous 

 in the future than it has in the past. At 

 present the canker is prevalent only in 

 Europe, but it has been reported from 

 Newfoundland so that the danger to Amer- 

 ica is imminent. The canker, works both in 

 dead wood and in the cambium, which it 

 gradually kills until eventually the tree 

 is girdled. Eradication of the canker, 

 which is one of the most virulent diseases 

 of forest trees, is practically impossible. 

 After it has once become established, the 

 maintenance of optimum silvicultural con- 

 ditions is emphasized as the best means of 

 prevention. 



Considerable space is devoted to various 

 heart rots and the honey fungus (Armil- 

 laria mellca). The latter is characterized as 

 probably the most destructive disease with 

 which British forestry has to contend. It 

 can kill all species of conifers and a great 

 many broadleaf trees, and in many woods 

 is so common that its eradication is well- 

 nigh impossible. The proper silvicultural 

 treatment and particularly the correct 

 choice of site, soil and mixture are recom- 

 mended as the best preventives for this 

 disease, as well as for the larch canker. 

 In the case of heart rots, frequent sam- 

 ple boring with a Pressler's increment 

 borer are recommended as a means of de- 

 tecting heart rot in its incipiency, so that 

 the affected trees can be removed before 

 they have been seriously damaged. Leaf 

 diseases are dismissed rather briefly as 

 less harmful than the needle diseases of 

 other conifers on account of the deciduous 

 habit of larch. 



The point is brought out that larch 

 is more prone to disease than any other 

 conifer commonly grown in British woods 

 and attention is called to the fact that 

 Douglas fir and Sitka spruce from Western 

 America are now being widely used in sit- 

 uations which would formerly have been 

 occupied by larch. Both trees are faster 

 growing than the larch and good returns 

 may be expected from them on suitable

soils, but with neither of them is there 

 such a ready sale for thinnings of all ages 

 as there is with the larch. Japanese larch 

 and western larch are nearly, but not quite, 

 immune from the canker, growing slightly 

 faster than the European larch during their 

 early years, and where grown on a short 

 rotation are safer and at least as re- 

 munerative as the latter. 



WAR MEMORIALS," one of a delight- 

 ful collection of poems by Abigail 

 F. Taylor, is published elsewhere in this 

 issue of American Forestry. Her book 

 comes from the press of Small, Maynard 

 & Company, Boston, and is called "Verse 

 of Today and Yesterday." It is well 

 named, the poems are full of feeling, in- 

 spired by the strongly real.
