compact, and consequently its-, position is indicated on the land 

 by beings slightly higher than the surrounding chalk-surface, 

 which appears to have been denuded at a more rapid rate. 

 Occasionally one of these sand pipes, in which no burial 

 occurred, has been mistaken for a barrow on account of its 

 resemblance to the artificial mounds. Similarly, these sand 

 pipes are occasionally met with on the Wolds during excavations 

 for chalk, and the accompanying block, illustrating a section in 

 a chalk-pit on Painsthorpe Wold, which has been kindly lent by 

 Messrs. A. Brown & Sons, shows a vertical section of one of them. 



Chalk Pit on Painsthorpe Wold. 



As no sand now occurs on the Wolds, these pipes are obviously of 

 great age, and in view of Mr. Stather's remarks it is interesting 

 to observe that the only pebbles found amongst the sand are 

 rounded quartzites, and they occur not uncommonly. 



When the excavations were being made in Cook's pit at 

 Hessle, some years ago, an item worthy of record was noticed. 

 These pits disclosed sections of sand, and angular chalk 

 fragments, surmounted by boulder-clay, the v^hole being banked 

 up against the pre-glacial chalk-cliff of Holderness. A great 

 part of the material below the boulder-clay had obviously been 

 w^ashed from the Chalk Wolds, over the cliff edge, on to the 

 old beach. Amongst this debris rounded quartzite pebbles were 

 occasionally met with. At one place, where the section was cut 

 to an unusually great depth, dozens of quartzite pebbles were 

 noticed amongst the large angular chalk fragments. The lowest
