124 NATUEAL HISTORY OF SCOTCH JFIB. 



habits which I had under treatment in a garden at Verrieres near 

 Paris ; the one forming a pyramid a little heavy and spreading, but 

 going up well and regular; the other, extending its branches 

 horizontally in such a way as to leave the trunk bare between the 

 crowns. I caused to be collected and sown separately the seeds of 

 these two trees, and their produce, planted opposite each other, are 

 now to be seen in the school. Both have preserved their original 

 characters in a very marked degree. Two thirds and more of the 

 individuals have the crowns ascending and pyramidal in the first 

 lot, while they are horizontal and spreading in the second. This 

 result being by much the most interesting aspect of the experi- 

 ment, I shall enlarge but little on what concerns it beside. 



" The pyramidal pine, from Verrieres, presents generally good and 

 promising trees, with a straight trunk and a regular crown ; the 

 bark is only one degree less marked than on excellent Eigas, which 

 approximates it to the pine of Guiparaz, or perhaps still more to 

 selected specimens of the Scotch fir, raised from seed supplied by Mr 

 Eeid." 



The third series, the German pine and the pine of Haguenau, is 

 characterised by having the branches ascending and extended, the 

 crowns irregular, and the branches often overgrown gourmandes. 



Of the typical tree of this series he writes : " Though more 

 vigorous than those of the preceding series, the Haguenau pine is 

 not so good as they. Its crown is too dense and too strong, often 

 intermixed with overgrown branches, which tend to destroy the regu- 

 larity of its trunk. It also frequently shows knees or defects which 

 greatly diminish its value. 



" The bark is reddish in most specimens, but it is not so uniformly 

 so as it is in the first seotion, or even as it is in the greater part of 

 the lots in the second ; that of the base is more brown and more rent. 



" The leaf is longer, more glaucous, and less pressed against the 

 twig than that of the elongated pyramidal seotion. The bud is less 

 forward in spring by eight or ten days." 



Under this third head he classes a pine from the forest of Haguenau 

 a pin sylvestre from Darmstadt, and a pinus sylvestris maritime/, received 

 also from Darmstadt. 



Of these he writes : 



" There are many clumps produced from seed obtained directly from 

 Haguenau, some sown, others planted, from 1823 to 1831.
