On the Enville estate the immber of roots hlowu to pieces was G4, 

 amongst whicli were some very large and tougli ones. An experiment had 

 previonsly been made by digging a hole and burying the root, but this 

 proved a very tedious and expensive method, besides which the firewood 

 was forfeited. 



The first experiment consisted of four very large elm trees in the hedge- 

 row. An auger hole 1| inches in diameter was bored in each and charged 

 with eight dynamite cartridges; the whole were exploded, shivering the 

 roots into fragments suitable for firewood. 



The second experiment was made on two large oak trees in the centre of 

 a field. These were simply charged with a few cartridges of dynamite 

 being placed in a natural crevice of the root without an auger hole ; the 

 charges were exploded, and the root blown into convenient pieces about 

 the field, suitable for loading up. 



The third experiment was made on an extraordinarily large ash in a 

 hedgerow, the fangs of which were very large, and lying undisturbed in 

 the ground, causing a serious obstruction to the plough. Underneath this 

 and between the ties several crowbar holes were made and charged with 

 dynamite, the fuses were all cut the same length and fired simultaneously, 

 blowing the whole mass out of the ground. 



The remainder of the roots were treated similarly, except that many 

 were broken up and blown out of their resting-place without an auger hole, 

 by placing dynamite in crevices or natural fissures of the stump. 



At the conclusion of the experiments, which lasted some few days, his 

 lordship said they had proved perfectly successful and quite satisfactory. 

 Mr. Eobert Cocks, his lordship's principal estate agent, supplementing this 

 by saying that from what he had seen of djinamite he considered it much 

 safer than gunpowder. 



Extent of Forests and Prices of Timber in 

 Scotland Sixty-six Years ago. 



By D, McKENZIE, Forester, Murthly, Perthshire. 



These are collected from a work by Sir John Sinclair, Bart. (1814), being 

 embodied in a general report on the agricultural, &c., state of Scotland at 

 that date, and may be of some interest by way of comparison with the 

 extent of woods and the prices of timber at the present day. The 

 total extent of woods in Scotland has not increased since then, but 

 rather diminished, the area under wood in IST-l being about 8G0,000 acres. 

 Some of the counties have added, others diminished the extent under wood.
