THE YORKSHIRE NATURALISTS’ UNION AT ASKERN. 291 
ecidiospores on TZhalictrum flavum. The latter is rather a rare 
Puccinia, and was first found in Yorkshire at Goole, by Mr. Birks, in 
June 1884. Since the meeting, Mr. Bunker, of Goole, has kindly 
forwarded additional specimens from that district, where it appears 
to be plentiful. There was very little of it at Shirley Pool Jungle, only 
one plant affected by it being seen. P. suaveolens Pers. on Carduus 
arvensis, Puccinia bullata Pers. on Conium maculatum, and Tri- 
Phragmium ulmarie (Schum.) on Spirea ulmaria were also met with. 
Ustilago segetum (Bull.) on barley was the only representative of 
the Ustilaginee. For obvious reasons it was not possible to give a 
list at the meeting. 
For the Geological Section the report at the meeting was given 
by Mr. Percy F. Kendall, F.G.S., and the following account is from 
the pen of Mr. J. W. Stather, F.G.S., of Hull, one of the Secretaries 
of the Section : 
The geologists first visited the large gravel-pit to the S.W. of the 
village, where the so-called Estuarine Beds are seen. This series of 
s had been altered a good deal by the progress of recent 
excavation, and consists now of (1) a bed of soft sandstone with lines 
of marly inclusions, the whole dipping steadily to the eastward. This 
bed was traversed by several faults which did not, however, affect 
the overlying beds. (2) A great thickness of coarse gravel with 
__ intercalations of sand. The stones in the gravel were gee 
Magnesian Limestone, rounded, sub-angular, or quite sharp, and 
ranged in size from small pebbles to blocks three feet in diameter. 
be bed rested upon an eroded, stepped surface of No. 1. No 
false-bedding was observed in the gravels or in the underlying sand- 
Stone. Prof. P. F, Kendall, who accompanied the party, expressed 
2 istance from the ae 
Summer more esp cially the melting of snow in the spring, 
would give rise to great rushes of water down the valleys, sweeping __ 
before them all the fragments of rock lying loose upon the surface. _ 
Along the eastern edge of the Magnesian Limestone, where it falls 
away beneath the Alluvial deposits of the Don valley, such streams — 
would probably drop their loads h t suddenly when they met _ 
the large body of relatively still water that seems to have occupied | 
the area during Glacial times. Such an explanation, Mr. Kendall 
had 
the opinion that the sandstone was probably of: Permian age, and a
