succeeds as not to be worth growing. Oats are grown on the Ham- 
bleton plateau at 350 yards, and produce moderate crops, as is also the 
case with barley ; but they occasionally fail altogether at that elevation. 
The highest garden is at 350 yards, where apples, gooseberries, cherries, 
raspberries, currants, and strawberries are grown ; also carrots, turnips, 
beans, peas, potatoes, cabbage, cauliflower, and broccoli are planted. 
The apple and cherry trees grow vigorously, but do not fruit freely at 
that place. There is one small patch of land enclosed from the moor 
at an elevation of 533 yards, where potatoes, common rhubarb, cabbages, 
turnips, onions, cress, and Sinapis alba have been cultivated: from the 
past tense being used, we presume that the success attained did not 
encourage a continuation of the attempt at their production. 
In the chapter on lithology, the effects of Eugeogenous (plentiful- 
detritus-bearing) and Dysgeogenous (sparing-detritus-bearing) districts 
upon the vegetation are largely and ably discussed. The results are 
shortly given :— 
“To sum up, then, the bearings of the subjacent ks upon the toy graphy of 
our North Yorkshire vegetation, as tested by a comparison of the distribution 
of species within our limits and in the country respecting which M. Thurmann 
treats, we may say— 
“1, As compared with the flora of Central Europe, the flora of North York- 
shire is one of a predominantly damp-loving stamp.

only occur in North Yorkshire in small number, and are there restricted litho- 
logically in a similar manner. j

And this shows us clearly that the nature of the subjacent rock 
and does interfere to modify the influence of atmospheric climate upon plant- 
topography, and it points out also in what direction the interference operates. 
A more porous and more humid soil evidently to some extent compensates for 
a drier climate. In proportion as the climate is damper, the e aracteristically dry-

This is the rule, and in botanico-geographical considerations it is evidently 
worth bearing in mind; but to what extent it has operated in determining 
which species we should have and which we should not have either in North 
Yorkshire or in Britain as a whole,—to what extent it has, for instan ted
