Forestry Exhibition at Norwicli, 1911. 287 



and planks of imported timbers with which the home grown 

 timbers have at present to compete. From the same place there 

 also came useful series of material showing the utilisation of 

 such native timbers as Ash, Elm, Beech, Alder, &c. Very 

 interesting also was the railway sleeper of creosoted 1)eech. 

 After being several years in use this sleeper was found to be 

 in an excellent state of preservation. Creosoted beech is largely 

 used in France for railway sleepers. Could not our own railway 

 companies be persuaded to try something in the way of utilising 

 beech and similar native grown timbers in like manner ? 



Included in the Cambridge collection were also sets of 

 specimens illustrative of forest botany, photographs of trees, 

 and various other exhibits. For this very educative and exten- 

 sive collection from Cambridge the Judges recommended the 

 award of the gold medal. 



The silver medal was awarded to Mr. E. R. Pratt for the 

 whole of his exhibits. Mr. Pratt showed, along with Messrs. 

 Prosser & Sons of London, a complete set of material illustrating 

 the whole process of manufacture of superior cricket bats from 

 Salix Alba ccerulea and also a less perfect kind made from 

 Salix frag His. The superiority of the ccerulea bats was well 

 brought out. 



Messrs. Prosser & Sons also had on exhibition superior ash 

 and other timber showing the manufacture of hockey sticks and 

 lawn tennis bats. Mr. Pratt's exhibit further included screens 

 made of black oak, and sections of ash timber grown on clay and 

 on peat ; also a section of a thorn hedge showing the beneficial 

 effects of the removal of elder plants and other objectionable 

 weeds when the hedge was renovated by "plashing." 



On Mr. Pratt's stand there was also exhibited a useful set 

 of micro-photographs prepared by Messrs. Flatters & Garnett, 

 showing the botanical features of the bat and crack willows. 



The Cooper Laboratory for Economic Research had a very 

 interesting stand on which were shown collections of material 

 illustrative of the damage done by various insects to fruit and 

 forest trees. This exhibit was awarded the bronze medal. 



Sir Hugh Beevor sent specimens showing damage done by 

 voles to young larch trees, and also photographs of British 

 Columbian trees. 



Lord Middleton sent a model of a useful creosoting tank, 

 along with specimens of timber creosoted. 



Messrs. Geo. Black & Sons, Berwick, exhibited a beautifully 

 finished model of creosoting plant by the pressure method. 



The Earl of Leicester had a stand of creosoted timber 

 which attracted very considerable attention. Very interesting 

 data concerning the amount of creosote absorbed by the 

 various species accompanied the sets of creosoted material.
