The following well-authenticated facts are given as 

 illustrating various interesting points in the history of 

 recently introduced conifers : — 



I. Dimensions and rate of increase for the List twelve 

 years of three large araucarias at Duns Castle, Berwick- 

 shire (]Mr. Peter Loney, land steward, Marchmont House), 

 last measurement, 14th September 1892. 



This table shows that three araucarias, averaging 5 feet 

 in girth 5 feet up, were growing at an annual rate of 

 1 inch ; that of the largest, upwards of 6 feet in girth, 

 being li inch. The circumference of the foliage of this 

 magnificent tree, thickly clothed to the ground, is 105 ft. 

 (D. Christison, 1893). 



II. Average rate of an araucaria, 27 feet high, and 24 

 inches in girth, at Stravithie House, Tifeshire, for twenty 

 years, at 5 feet up, 1-20 inch (Dr. Cleghorn, 1891).
