TATE: THE YORKSHIRE BOULDER COMMITTEE 69 
40 igneous rocks, they were, with two exceptions, andesites or 
andesitic breccias of Lake District types; the exceptions were :— 
1.—A block of the Quartz Porphyry of St. John’s 14 x 11 x 8” 
sub-angular and with no visible strie; and 2.—A block of Red 
granite less than a foot long: its source has not been recognised. 
The largest stones are the coal measure sandstones, which range up 
to about two tons weight. 
Baby (Pit belonging to Mr. Gibson) :— 
This pit shows the same bed of Boulder-clay. In carefully 
looking over many thousands of stones which covered the floor of 
the pit we could find only five igneous rocks, all Lake District 
andesites. 
Ba.py (Pit belonging to Mr. Cockin) :— 
We examined some thousands of boulders here (not, however, 
so many as in the last pit), and could find no igneous rocks at all. 
Woon’s SAND PIT :— 
Among the stones extracted from the boulder-clay at this place, 
was a Lake District andesite, and a specimen of Yoredale (?) 
limestone with Hyalonema parallela. 
Baxey (Beastall’s Sand-pit. 
In this excavation Boulder-clay rests on Triassic sandstone. We 
found Shap granite and Andesitic Agglomerate. These stones, 
we are happy to state, have through the instrumentality of the 
Doncaster Natural History and Microscopical Society, been secured 
for the town, and have been placed in the New Free Library.

YorK DISTRICT. 
Bi_proucn (Gravel-pit on the edge of the village). 
Pebbles of carboniferous sandstone, limestone, and chert; 
triassic red sandstone ; and magnesian limestone occur in the order 
of prevalence. A small boulder of Shap granite was found in 
a road-side heap near by. 
BiLproucH (Gravel-pit 400 yards E. of the windmill). 
A sandy clayey gravel was exposed containing stones ranging up 
to 1 ft. 6 ins. in diameter. Many of the stones were broken, and 
the fragments slightly displaced. A few stones, chiefly carboniferous 
limestone, were scratched. The varieties, in order of prevalence, 
were :—carboniferous sandstone, limestone, and chert ; triassic red 
sandstone; magnesian limestone; clay-ironstone; and dolerite 
(? Cleveland Dyke).
