and tramway sleepers, stobs, pit-props, and other pit timbers, 

 and several manufactured articles of the larger kind and also 

 some samples of fancy hardwoods. 



Among other exhibits was one of some nice clean pieces of 

 wood turnery from the Fechney Boys' Industrial School, Perth, 

 and various articles from the Lord Roberts Memorial workshops. 

 Interesting and high-class samples of home-grown timber, which 

 were sent in by timber merchants and others, were also on view. 

 The extraordinary rapid growth of Populus trichocarpa was 

 shown by two poles, cut in sections, from the Minto Estate, 

 which were respectively 7 and 14 years old. 



The kind of specimens exhibited by the Timber Supply 

 Department of the Board of Trade is shown in the following 

 summarised lists : — 



List No. 1 was devoted to converted timber, and contained 

 specimens of planks, sleepers, box boarding, waggon bottoming, 

 pit timbers, fencing rails and stobs, keel blocks, tool and 

 implement shafts, etc., and scantlings of various sizes, suitable 

 for hutting and house building purposes, in coniferous and 

 hardwood timbers. 



List No. 2 contained specimens of pith planks from the root or 

 first cut of various coniferous and hardwood trees. 



List No. 3 was made up of specimens showing the various 

 stages and the methods adopted in the conversion of logs and 

 tops into scantlings and articles of use in the employment of 

 timber. 



In this way the staging of the exhibit showed, by means 

 of actual samples, the various uses to which logs and tops can 

 be put, and how practically every requirement for timber had 

 been met, and can be met in future, from home-grown timbers, 

 if the supplies are augmented and maintained. 



List No. 4, headed Cross sections of logs, embraced a large 

 number of specimens, in which the transverse section of the root 

 cut of various coniferous and hardwood trees was exhibited to 

 show the quality of growth, year ring, and heart and sap wood. 



List No. 5 was made up of specimens to show the same 

 features, but in radial and tangential view. 



List No. 6 was composed of specimens exhibiting special 

 features, such as the bad results of leaving dead snags and 

 broken branches on the tree, bad effect of careless pruning, 

 occlusion of branches, etc.
