and lightly propose to plant it among broad-leaved trees in 

 coppice far above which the Douglas will quickly push as 

 isolated stems. We think it would be an excellent tree to 

 put, in bouquets say, in gaps in a high-forest beech wood ; 

 but coppice is another thing. M. Cannon has planted many 

 Douglas, and he finds that it grows superbly in moist sand. 

 Trees of 25 or 26 years old, planted among other conifers, have 

 a height of from 53 feet to 59 feet, with a diameter of 3 feet 

 to 3| feet. M. Cannon says it is certain that very calcareous 

 soils are unsuitable to Douglas. Roebuck are particularly 

 fond of the tree — possibly because of its aromatic needles. 



8. Mention was made last year {cj. vol. xxii. p. 47) of the 

 "June oak'' [Quercus pedu7iculata tardissma, Simonkai;. 

 M. Bauchery writes enthusiastically of this tree, which is to 

 be found in the centre of France, in Hungary, Bohemia, the 

 Crimea, and the Caucasus. In 1870 a certain young French 

 forest officer, M. Cu6not, was struck with the lateness in coming 

 into leaf of certain oaks, and since that time the variety has 

 been studied. It appears, then, that this June oak is superior to 

 the common pedunculate oak in that by coming into leaf four 

 to six weeks later it escapes spring frosts and insects {e.g., Tortrix 

 viridana, it may be assumed) ; its growth is more rapid, and 

 its shape is straighter. The density of its wood is 1*029; that 

 of pedunculate oak -911. Being somewhat pyramidal it no 

 doubt occupies less room, and can be more easily freed from 

 surrounding crowns. At the age of 60 years the growth of 

 the June oak is 3*5 per cent, faster that that of pedunculata, 

 and at 90 years 8 per cent, faster. M. Bauchery has noticed 

 that in a thicket of 18 years old the stems of the June oak 

 were consistently a metre taller than those of the common oak ; 

 and wherever it is met with it is ahead of the common oak of 

 similar age. Nor is this superiority due to growing in better 

 soil. The June oak may be found in all soils, and as often 

 in dry or very dry soils as in fresh and deep ones. In either 

 case it keeps the same lead. And whereas certain of the 

 common oaks will be mossy and stunted, the June oak 

 will be free from moss and doing well. The constancy of 

 lateness in this variety has been well established, even with 

 trees 130 years old. It should be added that the June oak 

 has no resemblance to the pyramidal oak {Q. pedunculata 

 fastigiatd).
