far,-at all events, as any force is concerned which so narrow and 
shallow a sea as the German Ocean can bring against it. These 
are some of the geological lessons to be learned from a_ walk 
along a shore like that of Mablethorpe ; and a study of the different 
sand-marks, tracks, and worm-casts; the thrown-up fragments of 
wood, shells, and other waifs of the sea, will go far to the 
correct reading and mode of deposit of similar ancient tidal shores, 
stg! done in stone—whether, for instance, they have been deposited 
a quiet or rough coast; whether any rivers or streams flowed 
ltd them, bringing the products of the land to mingle with those 
of the sea; or whether the region has been influenced by ice, in 
which case, as at Mablethorpe, stones and shells from higher latitudes 
will be met with ; and in solving many a questionable appearance 
which the student without such knowledge is very apt to mistake. 
Mr. Whistler’s note is as follows :-— 
The Roman bank is part of the great earthwork which runs the whole length 
of the Lindsey Marsh from Boston to Saltfleet, and I think still north again. 
A long stretch from Boston to Wainfleet is a as roadway, and, I am told, 
was metalled by the Romans themselves. It is so used again for about a mile at 
Saltfleet. A great deal of the bank has been carted on to the fields about here to 
improve sandy land. My Churchwarden, a farmer of 72, remembers well when 
there were no sand-hills over, or on this side of, the Roman bank (it is under 
the sand at Mablethorpe and below the Mablethorpe brick-field), and the sea line 
at that date was much nearer the Roman bank. He worked all one Sunday, 
with every available cart and man, at repairing a gap made in the bank bya 
heavy gale, some 60 years ago. This gives the date of the present sand-hillsas _ 
not more than 50 years ago. They have increased rapidly seawards during my 
five years here.
