paling along that front. The attempt was quite successful 

 and the hedge still stands, though the paling has been 

 replaced by an iron railing. 



When in England in 1865, I procured some plants of the 

 pink and crimson double hawthorn, so ornamental in that 

 country in spring, and planted them in different parts of 

 the grounds. One of them, planted in a rich and sheltered 

 spot, grew well and flowered several times. The others 

 were less successful, and eventually all succumbed to the 

 rigour of the winter. The common variety of the English 

 thorn is however more hardy. 



30. June-Berry. Wild Pear. Amelanchier canadensis. 



This beautiful little tree was introduced to the grounds 

 many years ago, and was the first to gladden our eyes in 

 spring with its white blossoms, though the wild plum was 

 sometimes about as early. I took special care of one speci- 

 men training it on a single stalk and cutting away the 

 shoots which this tree is so prone to form at the base. The 

 result was a specimen of unusually large size and beauty, 

 which several botanists informed me was the finest they 

 had seen. It was destroyed to make room for the engineer- 

 ing building. % 



On our grounds the delicious fruit of this tree, so much 

 prized by the Indians of the North-West, could not be 

 obtained, owing to the constant depredations of a grub 

 which destroyed or rendered it unsightly, and the birds 

 quickly disposed of the remainder. I had hoped by culture 

 to improve the fruit, but could never obtain it in any 

 quantity. 



31. Poplars. Populus. (Species.) 



The Abele or European white poplar and the Lombardy 

 poplar were early introduced on the grounds, and have 

 grown vigorously. The former is too rapid in growth and 

 too wide-spreading for limited grounds, and both are very 

 exhausting to the soil in their vicinity. Of the native
