EXTRACTS FROM PROCEEDINGS. 



lxxix 



Meetings lately, to an experiment I had made with coloured glass 

 in effecting a cross, by which, I believe, I brought out a white 

 from a pale-yellow Calceolaria. I am glad to see that some such 

 trials are being- made with tinted glass under the auspices of the 

 Committee. 



December 15, 1868. 

 A. Murray, Esq., in the Chair. 



The Minutes of the last Meeting were read and confirmed. 



A letter was read from Mr. J. Anderson Henry, in which he 

 stated his consent to comply with the wishes of the Committee in 

 conducting a series of experiments in accordance with the sug- 

 gestions in his previous communications. 



Mr. Berkeley reported on the specimens of Australian wheat 

 placed in his hands. 



The rust was evidently the common mildew ; and as regards the 

 Take-all, though it appeared very like a case of common blight, 

 there was a clamminess about the specimens which made it pos- 

 sible that they might be affected by the early stage of ergot. 



Dr. Masters exhibited a curiously puckered mushroom, which 

 owed its peculiar appearance to the attack of a parasitic Spliceria. 



Mr. Andrew Murray read a paper on the Pruning of Eorest- 

 trees. 



It was suggested that experiments should be made at Chiswick 

 to test the comparative merits of pruning and non-pruning, and 

 that Mr. A. Murray, Dr. Hogg and Mr. Berkeley should be a 

 Subcommittee with a view to inquire into the results of different 

 modes of planting. 



Dr. Hogg then made some remarks on the reciprocal action of 

 the graft and scion, the full consideration of the subject, how- 

 ever, being reserved for the n§xt Meeting. 



On Pruning Forest-Trees (by A. Murray). 



A great change has taken place within the last few years in the 

 minds of foresters and others in regard to priming forest-trees. 

 It used to be held an important part of a forester's duties, and 

 was spoken of as a kind of mystery which required initiation, like 

 astrology. Its high pretensions, however, have been considerably 

 abated ; and I believe I may claim some little credit to myself for 

 having helped to bring it about, by writing on the subject.
