Mr. C. J. Watson has pointed out a group of boulders between Northfield 

 and King's Norton. They occur in an excavation immediately above the 

 letter d of Northfield on the Ordnance Map. Eleven large and some smaller 

 are found within a radius of 20 yards ; and many others are scattered through 

 the fields immediately arormd and extending towards the railway. They are 

 of felstone and felspathic ash. The specific gravity of one of them was 2-63. 

 The following are the measurcmentsof the largest of the group: — F., 6' x 4' x 3' ;

llev. J. M. L. Aston, Vicar of King's Norton, reports a group of boulders 

 of greenish felstone, some of which are worked into the masonry of the 

 fonndation of the church-tower and others imbedded in rubbish. They are 

 subangular, and the exposed surfaces are often rounded. The largest is 

 6'x4' 6"xr C". 



A boulder of compact felstone has been found in Cannon Hill Park, Bir- 

 mingham, G' X 4' 3" X 4', rounded in parts and subangular, and to some extent 

 smoothed and polished. It was dug out of valloy-drift in making a lake. 



These Worcestershire felspathic boulders are probably from AValcs. They 

 are in positions which indicate that they have dropped from floating ice rather 

 than been deposited by land-ice. Signs of land-ice in the Midlands must be 

 looked for in boulder-clays at considerable depths beneath the general drift.
