Two of the trees mentioned by Lefroy as planted at Mount Langton by 

 Governor Eeid in 1845 existed there in 1914, having attained great size at the 

 base of the hill; the straight columnar trunks were then over five feet in 

 diameter and at least sixty feet in height. A few smaller trees may be seen
