compact and conical appearance. The branches grow each from a 

 sort of protuberance on the main trunk of the tree ; especially the 

 larger and lower branches. I have never observed cones. Nothing 

 is known of the history of the tree ; but, from its position, it is probable 

 that it was planted at the same time as those in its neighbourhood, 

 several of which are common spruce and silver fir, and are of much 

 greater size : perhaps 70 ft. or 80 ft. high.' 



" The specimens sent to us by His Lordship were considered by Mr. 

 Frost and Mr. Gordon, who have attended in a particular manner to 

 the ^bietinae, to belong to A. alba, or A. nigra, rather than to the 

 common spruce. We have subsequently received specimens from 

 Harewood House, which we have distributed among the nurserymen, 

 under the name of A. e. stricta. The gardener at Harewood has never 

 observed any cones on the tree ; which induces us to consider it as a 

 kind of monstrosity, like the last variety mentioned, and A. e. Clan- 

 brasilwwa ; the species being prone to produce extraordinary varieties 

 of this kind."

nication from the Rev. W. B. Clarke, A.M., 

 from which it appears that the barnacles 

 (Zepas r/natlfera) are found on the wood of 

 the spruce fir, as well as on tliat of the oak. 

 In February, 1834, part of the branch of a 

 spruce fir, with the bark on, was |)icked up 

 in Poole Harbour, completely covered with 

 barnacles. In fig. 2.'i4l., a shows a por-
