dently of aboriginal growth. Amongst the calcareous scars of 

 the west and upon the steep banks of the dales of the calcareous 

 hills of the east are the thickest and most extensive aboriginal 

 woods which we possess. Respecting the altitudinal range of 

 the indigenous trees details will be given afterwards. The 

 Juniper and Rowan ascend the highest and just reach the upper 

 limit of the Middle Zone. Above the Lower Zone thick woods 

 are rare and such as may be seen are often planted woods of 

 Larch and Spruce and Scotch Fir. Of the other trees which 

 are most usually planted the Horse-Chesnut and Popidus bal- 

 samifera both ascend to 350 yards. There is a natural wood 

 above Whitfield Gill near Askrigg at an elevation of 500 yards 

 and upwards and a plantation of larches on Askrigg Moor at 

 550 yards. 



The highest hawthorn hedge which I know is a little above 

 350 yards, and they are comparatively rare above 200 or 250 

 yards, the roads and fields amongst the moorlands being 

 generally bounded by stone walls. In favourable situations in 

 the low country the yield of Potatoes is 120 to 150 bushels per 

 acre ; of Wheat 4 to 6 quarters and exceptionally 8 ; of Oats 6 

 to 9 quarters and exceptionally 10 or even 12; and of Barley 

 6 to 7 quarters and exceptionally 8. Hordeuvi hexastichon is 

 cultivated but rarely and I am not aware that Avena strigosa is 

 grown at all. Rye also is but rarely grown. The other cultivated 

 crops of the low country are Turnips, Flax, Beans, Peas lyPisum 

 arvense and P. satwum), Mangold Wurtzel, and Brassica Napus. 

 Chicory is grown principally in the neighbourhood of York and 

 a field of Dipsacus fullomim is to be seen occasionally. For 

 forage Vicia sativa, Trifolmin prate?ise, T. repens, and Medicago 

 lupulina are principally planted, and occasionally Trifolium 

 incarnatu7n and Onobrychis sativa ; and of the Grasses Loliiwi 

 italicum and a host of others. Upon the argillaceous soils of 

 Cleveland the yield of Potatoes is from 150 to 200 bushels per 

 acre ; of Wheat 3 quarters and of Oats and Barley 4 quarters 

 each. Wheat succeeds best in the central valley and is very
