account of the more picturesque places we must refer the reader to the 
book itself. Then follows a series of tables of the more conspicuous 
plants, arranged according to their places of growth, and a short but 
interesting account of the plants cultivated on a grand scale. The 
principal cereal erops are rye, oats, and barley, of which the former 
succeeds well up to 600 metres; wheat is of comparatively recent 
introduction ; potatoes are grown largely, and are exported, and M. 
Crepin considers the district better. adapted for grazing-farms and the 
growth of forage and root-plants than for corn cultivation. Of the 
indigenous woods the Oak and Beech form the groundwork ; and 
in copses the Birch and Hornbeam are plentiful. The other frequent 
trees are Acer Pseudo-platanus and platanoides, the Ash, Salix Caprea 
and aurita, the Rowan, Rhamnus Frangula, Euonymus Europeus, and the 
Holly. * 
The subjacent rocks of the Ardennes are, as we have seen, entirely 
of the character which Thurmann calls eugeogenous. Comparing to 
gether the dysgeogenous Jura with the eugeogenous Vosges, Thur- 
mann cites twenty-four species which he considers contribute the most 
conspicuously to the general vegetation of the Vosges, but which are 
rare amongst or absent from the Jura. In the Ardennes, M. Crepin 
says, ten of these species are abundant and widely diffused, ten species 
are less frequent, and four entirely absent. Of the six species which 
Thurmann gives as most abundant in the Vosges, as opposed tothe J ura, 
five are common Ardennes plants. These are Sarothamnus scoparius, 
Aira flexuosa, Jasione montana, Betula alba, and Luzula albida. 
flowering plants and ferns which the district produces. We are glad to 
see that pains have been taken to separate the species likely to be really 
indigenous. Excluding the former and using about the same standard 
of what are species as is employed in our London Catalogue, 663 plants 
are enumerated, out of which, in glancing through the list, we have 
counted only 44 species which have not a tolerably fair claimt be ga rded 
as British. As might be expected, very few of these are species running 
out from Central Europe in a northern and western direction, which 
sketch is comprehensive in its plan, and seems very careful as Te 
matters of detail, and is well worthy of the attention of botanists.
