the first three are part of the eotintry of the Carboniferous rocks, and 

 the others of that in which granite and metamorphic rocks occur, 

 followed by notices of the drift, alluvium, mines, minerals, etc. The 

 author considers there are three well-marked classes of the drift, 

 viz., Boulder- day drift, Boulder drift, including rocky boulder drift 

 and EsTcer drift, the first supposed to be of marine origin, the second 

 of glacial, and the third or Eslmr to be the two former, well washed 

 and sifted, perhaps by marine and tidal currents. Some notes on 

 denudation, dressed rocks, striee, etc., are given, accompanied by a 

 table of supposed ice striae, grouped according to the parts of the 

 glacier or its branches to which they belonged. 



Space will not allow of our entering more fully into the very ex- 

 tensive details of the descriptive geology of this Memoir, which 

 nevertheless cannot fail to be of great service to those geologists 

 whose travels may take them into this interesting district. 



III. — Journal of the Eotal Agricultural Society of England. 

 2nd Series. Vol. v. Part ii. 1869. 



IN the Eeport of the Council of the Eoyal Agricultural Society, 

 read at the General Meeting of the Society in May, 1869, it 

 was pointed out that although their Journal contained valuable 

 reports on the Agriculture of most of the English Counties, yet 

 several years had elapsed since many of them were written, and 

 that, in the present state of Agricultural practice and science, there 

 was still much of interest to record in different localities. It was 

 therefore advised to obtain more detailed information as to the 

 management of particular districts, and to record anything peculiar 

 in the system pursued upon special farms, to which gentlemen, 

 deputed by the Council have recently paid visits. 



In the Journal now before us are seven Eeports on Farms, pre- 

 pared either by Mr. H. H. Dixon, or by Mr. H. M. Jenkins, F.Gr.S., 

 the Society's Secretary, who visited the farms, accompanied in every 

 case by a Member of the Council. 



The reports are arranged geographically, as nearly as possible, 

 commencing with a hill farm in the north, which is a gigantic sheep- 

 walk, yielding only pasturage and mountain-hay, and coming gra- 

 dually southwards through the Yorkshire Wolds, North Lincoln- 

 shire, Nottinghamshire, Norfolk, and Worcestershire, to a Wiltshire 

 sheep-farm, which yields enough grass and green food to support a 

 breeding ewe to the acre. 



Various points of interest, and much useful practical information, 

 are contained in these reports ; the subjects treated of are — Geology 

 and physical features, fences, drainage, ponds, grass-laud, arable- 

 land, manures, horses, cattle, sheep, pigs, labour, and farm buildings. 

 As Mr. H. M. Jenkins has so lately been appointed to the post of 

 Secretary to the Eoyal Agricultural Society, from the Assistant 

 Secretaryship of the Geological Society, it is natural to find that from 

 every farm which he visited we obtain an insight into its geological 

 features, which adds a fresh interest to these reports for the farmer.
