II. Girth at 5 feet up of some of the finest conifers at 

 Castle-Kennedy, Wigtownshire (Mr. William Cruden, 

 gardener, December 18911 



III. Dimensions and rate of girth-increase of the best 

 conifers of all the species at Dolphinton and Methven, 

 selected from the. Conifer Conference Statistics, 1891, 

 because their age is known with exceptional precision. 



Mr. Ord Mackenzie has kept a regular record of the 

 planting and progress of his conifers at Dolphinton. They 

 w^ere planted when about 18 inches high, and I have added 

 two years to the date of planting for their growth to 5 

 feet. The Methven trees were raised from seed, or 

 cuttings, or planted as seedlings 2 feet high. I have 

 added only two years to the date of planting for all for 

 growth to 5 feet.
