could get from the home timber merchants, and had to get 

 the rest elsewhere at the lowest price they could. In concluding, 

 Mr Chrystal promised that the railway companies would give 

 due consideration to the whole matter as placed before them 

 by the delegates. 



Captain Stirling then moved a vote of thanks to the 

 Chairman and the Representatives of the railway companies, 

 and stated that the deputation had not expected a definite 

 reply then, but were glad to know that the railway companies 

 would consider the case that had been put before them. 



Note. — Since the date of the meeting several of the Scottish 

 railway companies have agreed to buy sleepers of home-grown 

 timber at the same price as foreign sleepers. It is hoped that 

 in response to this concession an effort will be made by the 

 timber trade to ensure a regular supply of sleepers of such a 

 quality as will challenge comparison with the foreign article. 

 The Landowners' Co-operative Forestry Society have already 

 undertaken contracts for the supply of sleepers at 4/5 each 

 delivered.

 Edinburgh, and MALCOLM Wilson, D.Sc, F.L.S., Lecturer on 

 Mycology, University of Edinburgh. 



On the 22nd May 19 12, Mr Donald Grant, forester to Sir 

 John Stirling-Maxwell on his estate of Fersit in Inverness-shire, 

 sent to one of us specimens of Larix ei/ropaa with a fungus 

 disease on the leaves, which, he remarked, bore a striking resem- 

 blance to the pine leaf rust, Feridermium pint f. acicola. 



An examination of the specimens in the laboratory leads 

 to the conclusion that the fungus present must be provisionally 

 included in Peridermium, a genus of the Uredineae, consisting 

 of a number of species parasitic on Gymnosperms, of which only 

 the aecidial stage is known. Klebahn,- in 1898, described a 

 species of this genus parasitic on the larch, which he named
