different species to be made use of and methods of mixing 

 them ; the question of forming mixed crops of (i.) shade-bearers, 

 (ii.) shade-bearers and Hght demanders, and (iii.) light demanders, 

 is discussed. 



Chapter IV. treats of nursery management, deahng with the 

 matter on the ordinary Hnes. There is a useful little table on 

 PP- 54j 55> showing the seasons to gather seed, to sow it, the 

 depth of covering, the number of plants to be expected from i lb. 

 of seed, and other useful information. The species dealt with are 

 ash, alder, beech, birch, elm, hornbean, oak, sycamore, sweet 

 chestnut, Austrian pine, Corsican pine, Scots pine, Weymouth 

 pine, silver fir, Douglas, spruce, larch and Japanese larch. 



Sowing and planting in the forest is then treated upon general 

 lines. Some figures are given contrasting the difference in cost 

 of planting home-grown and purchased British and foreign 

 plants. The difference is in favour of the home-grown plant. 



Some brief notes are given on the tending of woods, and 

 on the various silvicultural systems, termed by the author 

 " Methods of Treatment." 



Three chapters are devoted to " Protection of Woods " — an 

 all too short a space necessitated by the object of keeping the 

 book small. 



There is an interesting note under Weeds on p. 127. After 

 pointing out that a growth of birch, sallow, aspen or coppice 

 shoots of any species should not be cut back in a young 

 plantation without taking into consideration the fact that they 

 may be affording shelter from frost, wind, etc., to the young trees 

 being raised, the author says, " A very good instance of this 

 sheltering effect of what would ordinarily be called weeds can be 

 seen in the Crown woods at Tintern, where an excellent crop of 

 larch, Douglas fir and Scots pine, in groups, over about ten acres 

 in all, has been raised on a somewhat exposed position, at an 

 elevation of 850 feet, by leaving coppice shoots of oak and other 

 woody weeds on the ground, the crop being planted between 

 them. The area was gone through occasionally, and, at very 

 small expense, just those shoots which were actually injuring a 

 tree being cut back. The trees have now been planted eight 

 years and are forming thicket, and the coppice shoots will be 

 left alone to die out." 



Chapters XI. and XII. (30 pages in all) are devoted to silvi- 

 cultural notes on hardwoods and conifers, followed by a useful
