We will just briefly notice some of the geological features of tlie 

 reports. 



Taking them in order, we have — 



1st. A Kill and a Half-Hill Farm (Teviotdale). By H. H. Dixon. 

 — This report contains no geological references. 



2nd. Eastburn Farm, near Driffield, Yorkshire. By H. M. Jen- 

 kins. — This farm, which contains about 1,300 acres, is situated on a 

 spur of the Yorkshire Wolds. 



Accompanying the report is a small map showing the surface-geo- 

 logy, after a survey by J. E. Mortimer, Esq. of Fimber ; and also a 

 brief description of the geology of the Wold range by the same 

 gentleman, who is a well-known local geologist and antiquary. 



Three kinds of subsoil are found to overlie the Chalk which forms 

 the Wolds, two of which are represented on the Farm. 



The first and most extensive is a small Chalk-rubble, with flints 

 of various sizes derived from the Chalk beneath. It occurs on the 

 northern and western escarpments of the Wolds, and on the southern 

 and eastern slopes, where it attains a thickness varying from four to 

 eight inches. 



The second subsoil is a Drift-clay, sometimes containing, and at 

 others replaced by, beds of a sandy nature. It covers the Chalk to 

 a thickness of from 1 to 4 feet, and in places contains a great quan- 

 tity of native angular flints stained with ferruginous matter. The 

 soils on this deposit, which is mostly found on the hill-tops and the 

 northern and western sides of the Wolds, are cold and ' unkind,' 

 though deep. The deposit itself seems of a somewhat similar cha- 

 racter to the " Clay-with-flints," which rests on the Chalk in some 

 of the southern counties. 



The third subsoil is a gravel, containing angular and subangular 

 flints, with rounded fragments of granite, trap, quartz, sandstone, 

 etc. It occurs on the bottoms of most of the Wold valleys, and in 

 some places extends a little way up the sides of the hills. 



Eastburn Farm contains, in addition to the last two of these sub- 

 soils, some " slightly raised banks of Chalk-gravel, between which 

 are beds of peat, and occasionally clay," and also a loamy clay, 

 which underlies these. 



The gravelly land was very sterile, but a liberal supply of manures 

 has rendered it tolerably productive. 



3rd. Aylesby, Biby, and Bothwell Farms, near Grimsby, Lincoln- 

 shire. By H. M. Jenkins. — Boulder-clay, Silt-loam, Chalk-rubble, 

 and Chalk are represented on these farms, which cover an area of 

 2,080 acres. These sub-soils all appear to have a loamy top-soil. 



4th. Nottinghamshire Farming. By H. H. Dixon. — Two farms in 

 South Nottinghamshire are here noticed by Mr. Dixon. Geological 

 notes are also contributed by Mr. Jenkins. 



5th. The Lodge Farm, Castle Acre, Norfolk. By H. M. Jenkins. — 

 The geological features of the ground occupied by this farm are 

 briefly pointed out ; the deposits represented are the Brick-earth of 

 the Nar, Boulder-clay, Drift-gravel, and Chalk. The Boulder-clay 

 caps the Chalk-hills, the gravels occupy the valleys, but, as pointed
