piled a valuable report on the whole subject, which extends to 

 208 pages. 



Pomology was, indeed, one of Mr Dunn's strongest points. He 

 could pick out all the apples in a large collection and name each 

 in turn, and fruit was sent to him from all parts of the country 

 by people who desired to have it properly classified. 



A plum congress was held in September 1889, and again 

 Mr Dunn edited a report upon it, extending to 164 pages. These 

 are not of the nature of ephemeral works, but have to gardeners 

 a practical value at the present day. 



During all the years he was connected with it, Mr Dunn was a 

 leading man in the councils of the Royal Caledonian Horticultural 

 Society, and the assistance he gave at the time of its spring, 

 summer, and autumn exhibitions was of a liberal and invaluable 

 kind. He was also one of the prime movers in procuring for 

 this ancient Society a new charter, which has launched it afresh 

 on what its friends hope will be a career of new usefulness. 



In this connection reference might be made to Mr Dunn's 

 successful treatment of the vine disease {Phylloxera vastatrix), 

 which destroyed many of the vineyards in the south of France 

 and other Continental countries, and also proved itself a plague 

 in some of the vineries at home. Mr Dunn succeeded in destroy- 

 ing the insect, which passes the winter season on the roots of the 

 vines, and his specially written paper for the Practical Gardener, 

 edited by Mr James Anderson, was a valuable contribution to 

 the literature on this important subject. Notice might also be 

 taken of his " Statistics of the Conifers in the British Islands,'" 

 which was reprinted from the Journal of the Royal Horticultural 

 Society, vol. xiv. — Conifer Conference. It is for all foresters a 

 most useful pamphlet. 



Mr Dunn was also a founder and an enthusiastic supporter of 

 the Scottish Horticultural Association, and in the promotion of 

 the educational schemes of that body, and at its annual Chrysan- 

 themum Show, he was ever to the front. He was also a member 

 of the Edinburgh Botanical Society. In connection with this 

 aspect of his career, the Regius Professor of Botany, Professor 

 Bayley Balfour, says : — " Mr Malcolm Dunn's knowledge of the 

 plants of cultivation was remarkable, and he knew them in the 

 best of all ways, by the cultivation of them. At the same time, 

 he had a ready store of book knowledge of their history. There 

 was no one in Scotland to whom one could apply with more
