    The mean annual increase at different ages is as follows :— 45 years = 4.5 lines (8 at Kinmundy.) 100 ... =: 4.04 ... (3 at Huntly.) 100 ... rr: 4,05 ... (8 at Newe.) 150 ... = 4.02 ... (2 at Invercauld.) 2:0 ... == 2.4 ... (2 at Leith Hall.) 800 ... 1.7 ... (8 at Striclien.) The ash is generally of very rapid growth ; this, however, does not render its timber less valuable, but rather the reverse ; for Mr Campbell, an experienced timber-merchant here, informs me that the value is nearly directly as the rapidity of growth. A section of an ash at Colquhonnie, in Strathdon, shewed 111 annual zones. Its girth at the soil was 9 feet 5 inches ; the pith was rather eccentric. The following will shew the increase at different periods : — Zones 1 to 10 1 inches. 10 to 20 = 2 20 to 80 = 2 ... 80 to 40 = 1.5 ... 40 to 50 = 1.25 ... 50 to 60 = 1 ... 60 to 70 = 1.25 ... 70 to 80 = 1.12 ... 80 to 90 = 1 90 to 100 = 0.8 ... 100 to 111 = 1.8 A fine example of the ash in the vicinity of Aberdeen, which was planted on the day on which the battle of Culloden was fought, now measures nine feet four inches at six feet from the soil. Ulmaceai:.—JJlmus montana,—The Scotch Elm. In none of the reports was any distinction made between the Scotch and English elm ; the former, however, being common, and reach¬ ing considerable dimensions in this part of the country, it is probable that all the measurements had reference to it. This tree is often seen associated with the ash, sycamore, gean, and mountain-ash, near ruins and former seats of small proprie¬ tors, so numerous at one time. It is very general throughout the county ; and if we may judge from the luxuriance of it at Invercauld, in the heart of the Aberdeenshire Highlands, and
