with its continuation Loch Doine, and Loch Lubnaig is apparently 

 only nine feet. The rise and fall in Loch Lubnaig is estimated as 

 about six feet, and this slight difference of level requires careful 

 consideration. It bears out the theory that in early times Lochs 

 Doine, Voil, and Lubnaig formed one sheet of water.

The proposal to erect a fish pass at the Falls of Tummel has 

 been made time and again for many years. It cannot, therefore, 

 be said that negotiations with this object in view were recently 

 commenced, but on 4th June, 1907, a meeting took place in Fask- 

 ally House between the Marquis of Tullibardine, Mr. Barbour of 

 Bonskeid. Mr. Charles Butter, Faskally, Mr. H. W. Johnston, and 

 myself, which formed the genesis of a successful arrangement. As 

 a result of the meeting a draft memorandum was prepared which 

 touched upon the site of the proposed pass, the compensation to 

 Mr. Barbour by way of his acquiring a lease or the purchase of 

 rights of fishing ex adverso Bonskeid above the Fall, which rights 

 at present belong to the Duke of Atholl. At the same time the 

 payment of costs in constructing the pass was discussed. After an 

 interval, during which necessary advice was obtained and possible 

 terms of agreement ventilated, Mr. Barbour decided to offer to 

 purchase the right of fishing ex adverso Bonskeid Estate. I have 

 pleasure in reporting that the offer to purchase has now been 

 accepted, and that as a result the erection of a pass at this 

 important fall may be expected to proceed during the coming 

 summer. 



Two other streams which have from the beginning of time 

 offered obstruction to the ascent of salmon in this district 

 have recently been dealt with. Both streams are, so far as 

 the obstructions are concerned, the property of the Duke of 

 Atholl. 



The Tilt, which falls into the Garry at Blair Atholl, drains two 

 of the Duke's deer forests, and could only be ascended by salmon 

 with great difficulty. The worst falls of this river, about two 

 miles above Blair Castle, have now been blasted and entirely 

 removed.
