NOTES AND QUERIES.

from storms and were practically staghorn-headed, and tapered 

 very much in the trunk. They were cut into lengths averaging 

 8 feet, and each tree throughout showed a great amount of 

 red heartwood, which seemed to darken on exposure to the 

 air. It is proposed to convert the trees, at the estate sawmill, 

 into planking for steadings, 2 ins. and i| in, trevicing. 



The Douglas fir at Forglen, even in a young stage, has 

 proved itself of greater durability than Scots pine for fencing 

 purposes.

Height-Growth in Conifers Compared. 



In a previous number of the Transactions I gave some 

 particulars of tree-growth, since then I have made periodical 

 measurements of conifers growing on a fairly good forest soil, 

 planted in 1908, partly in groups and partly mixed. The average 

 height over the entire plantation is about 10 feet. I give 

 below the figures for two growing seasons. The measurements 

 described were taken from trees that had made a normal growth 

 the previous season, different trees being selected each year. 

 One of each variety only was measured, the selected tree being 

 specially marked at the beginning of the growing season. 



I don't know if it is generally realised that Scots pine has 

 nearly finished its season's growth before the larch begins 

 to grow. 



It will be noted that the Scots pine made practically all its 

 growth in May and June; the Insignis pine. May to July ; Finns 

 Pinaster, May to September; Douglas fir. May to October; 

 European and Japanese larches, June to September. A close 

 study of the table overleaf suggests some serious thoughts
