one or two places, but it is perhaps in the serviceable illustrations 

 which have been added that the chief increase in the value of 

 the book is to be found. 



The former editions, it will be remembered, included diagrams 

 of various forms of fencing, forest implements and illustrations 

 on methods of planting out transplants. In the present volume, 

 additional illustrations on these matters have been added, whilst 

 some most useful diagrammatic representations of the various 

 silvicultural systems are included. These will be found of high 

 utility to the student who wishes to make himself acquainted 

 with the different systems. 



In the portion of the work dealing with the Formation and 

 Regeneration of Woods, Sir William Schlich has incorporated 

 some useful photographs illustrative of different classes of woods 

 in various stages of growth. Natural regeneration in various 

 stages coming in beneath the shelter-wood is shown very well 

 in some of the photographs. The reproduction of some of the 

 negatives, or the negatives themselves, however, leave some- 

 thing to be desired. 



The part entitled " Silvicultural Notes on British Forest Trees," 

 has been augmented by the inclusion of remarks on Robinia 

 and the walnut amongst the hardwoods, and the Menzies or 

 Sitka spruce, white spruce, Thuia plicaia, and Tsuga Alberiiana 

 amongst the conifers. The notes on other species have also, in 

 some instances, been revised and lengthened. 



Under the Douglas fir, the author has some interesting remarks 

 on the damage occasioned to this tree by storms. In Bagley 

 Wood, near Oxford, trees planted eleven years ago and 30 feet 

 high were thrown in December 1909. Even the plants in a 

 plantation made three years ago were laid low three times during 

 the winter of 1909-10, and this in spite of their enjoying a fair 

 amount of shelter from the west and south. Sir William holds 

 the opinion that the tree is slow in developing a sufficient root- 

 system in Britain, so that it is easily thrown by the wind, 

 in especially wet weather ; and even if not thrown the leading 

 shoots suffer from being broken or bent. 



The author puts in a plea for the silver fir. After describing 

 the growth of the Taymount plantation of Douglas fir, planted 

 by the late Mr M'Corquodale about i860, he writes: "He 

 (M'Corquodale) held the opinion that the silver fir, if grown and 

 treated in the proper way, would be the most useful and profit-
