beneath and placiug a few cartridges in the hole thus made. A cheaper 

 mode of removing boulder stones is by making a hole, say seven inches 

 deep, in a stcns weighing a ton or two, putting a two-ounce cartridge of 

 tonitein, and pressing the earth in and covering it up with a shovelful of 

 clay, -wh-en it will split the stone, so that it maybe removed by a couple of 

 labourers. 



Tree stumps may be removed cither by boriug holes with an auger and 

 putting a cartridge into each, or by making a hole under the roots and 

 placing a few cartridges in it. 



The stump will thus be burst up or riven, so as to be easily cut or dug 

 out and cleared away. When more than one hole is bored in a heavy 

 stump, and many to get out of the way of danger, I would recommend 

 firing by electricity, as the whole will go off at once, and materially assist 

 each other, for large stumps will require a charge in several places to 

 burst them up effectually. 



Tonite is six times the strength of ordinary blasting powder, and has a 

 peculiar downward tendency, which is of much advantage in the operations 

 of clearing land. The price is 2s. per lb., which, on taking the strength and 

 efficiency of tonite into account, is much cheaper than blasting powder, as 

 smaller charges are required ; and as it will go off under water, much 

 time and labour is thus saved, besides being the safest explosive known. 



I shall be happy to communicate with any gentleman requiring further 

 information on the sul;)jeci". T. Dineen.

THE CTJLLEN PRICES. 



Sir, — I will now fulfil my promise of last month (see page 276) 

 regarding my remarks on the *' Cullen Prices" at page 114, signed 

 "Ancora Imparo," and Mr. Michie's unsatisfactory explanation of them at 

 page 195. In a few preliminary remarks I will state how my attention 

 Avas drawn to the prices quoted from Cullen at page 31, and then pro- 

 ceed to give my authorities for challenging their correctness, and also give 

 the average prices obtained in and around this neighbourhood. 



Upon the issue of the first number of the Journal of Forestry I was, 

 as may be easily iuiagined, eager to peruse its contents, and amongst 

 other valuable and interesting matter I closely scanned the " Table of 

 prices of Forest Produce in Great Britain," and naturally enough felt sur- 

 prised at the high prices said to be realized in this county. Soon after 

 this 1 had occasion to attend a meeting of several wood merchants and 

 foresters, when the recent appearance of our new Journal of Forestry was 

 mentioned, and after some conversation the subject of the high prices 

 quoted from Cullen was brought up and discussed, with the result that 

 no one present would believe that such extraordinary prices could be got 

 in this district, at Banff or Cullen, either by private sale or at public
