300 The American Geologist. NOvomber, 1895 
The <'rin()i(lal limestone under it I will not attempt to corre- 
late, as that can best be done by means of its paleontologic 
relations ; and the basal sandstone is undoubtedly only a 
local development, depending on local conditions, and there- 
fore not to be correlated with any sandstone formation in other 
parts of the country. 
GEOLOGY AT THE BRITISH ASSOCIATION FOR 
THE ADVANCEIVIENT OF SCIENCE. 
By E. W. Clatpole, Akron, Ohio. 
The sixty-fifth annual meeting of the British Association 
for the Advancement of Science began at Ipswich on Wednes- 
dav, September 11th. Ipswich is a town of about 60,000 peo- 
ple, situated on the east coast of England. It was the birth- 
place of cardinal Wolsey and many of the historical incidents 
and waymarks of the jilace are connected with him and the 
events of his life. 
The department of geology was well represented and some 
old familiar faces were present. The president of the section, 
Mr. Whitaker. delivered an address on the underground waters 
of Suffolk, tracing their origin and fiow in an imaginary sub- 
terranean excursion. The rest of the day was spent by many 
of the sectional members in an excursion to the chalk pits and 
Eocene beds at Braniford. 
On Friday morning sectional work began in earnest with a 
paper by Prof. Sollas. of Dublin, on the action of pitch in some 
artificial glaciers of that nuiterial, with which he had been ex- 
perimenting. Placing a mass of ])itch in such a position that 
one end was higher than the other he ilistributed foreign ma- 
terial of various kinds in the mass and placed obstacles in its 
path. On examination after an interval of several w^eeks he 
foimd that almost all the planes then formed in the pitch 
had been bent up on meeting each obstacle and had formed 
curved lines of flow over it, returning approximately to their 
former course after having passed it. In this way he proposed 
to explain the elevation of glacial detritus, such as perched 
blocks, from lower to higher positions. He quoted in support 
of his views some photographs taken by Prof. Chamberlin in 
XJireenland in which stones and other material were seen en- 
tering the ice at the side of the glacier and riding through it.
