to trunks, crowns, and bark, they are in general rather passable, or 

 mediocre than good, or very good." 



The second grand division consists of those with horizontal 

 branches,* among which we find the fourth section, designated the 

 horizontal tapering, of which the type is the expanded elongated pine 

 of Geneva, of which M. Vilmorin gives the following characteristics : 



'* The branches, spreading horizontally, sometimes even depressed ; 

 generally very much elongated and flexuous ; united in regular 

 cx'owns, which leave the trunk bare in the intervals between these. 

 This is rarely very straight ; the curvations not so acute as on the 

 Haguenau ; but, on the other hand, its grossessement is much less. 



" Tlie bark is tolerably red in some of the lots of this race, but 

 more commonly grey^ or very much mixed with grey. 



" The leaf is larger and shorter than in all the preceding series. 

 The bud in spring later by from eight days to a fortnight in ex- 

 panding." 



Under the fourth head, the horizontal elongated but straggling 

 Geneva pine : a section of the trees having horizontal branches, he 

 classes — The Ard^che pine ; the Geneva pine ; the Tarare pine ; the 

 pin sylvestre di(, Maine ; pines raised from the seed of a specimen, 

 having straggling branches, growing at Verrieres ; a pin sylvestre, given 

 as a Riga pine by M. Leblond, of Bordeaux ; and a pinus sangidnea, 

 received from M. Barthude, of Toulouse. 



Of the three first mentioned he writes : " Though of different ages, 

 the first sown or planted in numerous masses from 1823-1831, the 

 second planted in mass in 1840, the last planted in row in 1833 and 

 1835, they have always appeared to me identical ; I include, there- 

 fore, the whole in the same description. I give the preference to the 

 Ardeche pine, because, being the eldest of the three, and by far the 

 most numerous in the school, it best represents the series to which 

 it belongs, and may therefore give of it the best idea. 



" The trunks in this race are in about half of them pretty straight and 

 elongated, but too much swelling out and drawn out in rat-tail form. 

 The other half present knees more or less decided, but less strongly 

 so, than in the bad types of the Haguenau pine, and in the sylvestre 

 of the High Alps previously described. The branches, excepting those 

 of two or three of the higher crowns, are very generally horizontal, and 



^Corresponding to the Pinus Sylvestris Vulgarit.
