the centre when it becomes old. The centre timber very 
soon becomes short, and decays in most of the kinds. The 
timber is remarkable for its lightness and softness; that of 
tremula is the hardest and heaviest of any species when grown 
in firm soil The softest and lightest wood is that which is 
fast grown, on rich, soft, mossy ground. In remote districts 
throughout the country, where its uses were unknown till 
lately, 1 have known it to be sometimes sold at sixpence per 
cubical foot, and cheaper than any other wood ; but since its 
uses are become better known, it often fetches the usual prices 
of the different kinds of hardwood. The wood of all the 
species contracts very much on being seasoned. It suits all 
the purposes of willow timber. It is esteemed for cladding 
for carts, waggons, barrows, railway-trucks, and the like. Em- 
ployed as such it does not splinter like most kinds of deal, 
nor crack in the driving of nails) When struck, the blow 
only indents the soft wood, without piercing or cracking 
it. Its lightness recommends it for many purposes, such as 
doors and gates, more especially such as are of great dimen- 
sions and in frequent use, where heavier wood is apt to strain 
the hinges. It is also esteemed for kitchen furniture, dishes, 
rollers for silk, carver and cooper work, butchers’ and bakers’ 
trays, and all purposes where a clean appearance and lightness 
are a recommendation: On the Continent it is the common 
wood for clogs, and various small wares; of late it is much 
sought after, on account of its softness, for railway brakes, it 
being difficult to ignite by friction.
