4*78 Canadian Record of Science. 



above is a very slight sketch of Mr. Milne Home's multi- 

 plied labours and public engagements. He was the author 

 of many reports, public addresses, and memoirs on a great 

 variety of geological, archaeological, and other scientific 

 subjects ; and from his position and personal character 

 exercised a large influence in favour of science and educa- 

 tion in Scotland. 



The few facts above stated are gleaned from the well- 

 written biographical sketch from the pen of his accom- 

 plished daughter, Miss Grace Milne Home ; l in which will 

 also be found interesting notices of the geology of Ber- 

 wickshire, and letters from eminent geologists and other 

 scientific men, with whom Mr. Milne Home was in cor- 

 respondence. J. W. D. 



Addenda to Sir "W. Dawson's Paper on the 



Trees Growing on the G-rounds of 



McG-ill University. 



In the discussion I was reminded that I had omitted two 

 of our most useful and beautiful shrubs, the Mahonia, 

 Berberis aquifolium, and its ally, B. vulgaris, both of which 

 'may be said to have been naturalized on the College 

 grounds and spread themselves at their own discretion. 

 The former in particular is interesting as our best substitute 

 for Holly, which in its foliage it much resembles. It 

 is an evergreen, but its leaves are liable to be killed in win- 

 ter if not covered with snow. When planted in a low and 

 sheltered place, likely to be well covered with snow in win- 

 ter, it spreads freely and its leaves preserve their greenness, 

 so that it may be gathered at Christmas ; and it will come 

 out bright and uninjured from under the snow in spring. 

 With a few of the berries of the tree cranberry, which 

 remain red and perfect all winter,it may be made to do duty 

 very well for the traditional holl}< of the mother country. 



It was also noticed in the discussion that the growth of 

 trees in this climate is very rapid. A young man who 

 plants well selected trees may, before he is middle aged, 

 have large and useful plantations ; and belts of forest trees,
