YORKSHIRE NATURALISTS UNION. 
difference in the two areas, the line of the Craven Faults beingf 
taken as the critical reg-ion. It is a problem that Yorkshire 
i^^eologists must face, and solve if possible. At Loftus it was the 
famous Cleveland Ironstone that demanded attention, though in a 
district so full of geological interest it was only one among many 
other interesting features. It had this difference, however, that 
from its immense economic value to the county, it calls for every 
effort to elucidate its genises and extent. The strong recommen- 
dation from the meeting that an effort should be made during the 
next season to devote the necessary time for a thorough investi- 
gation of this most important deposit, will, it is hoped, receive the 
sympathetic consideration of the Union. At Pocklington, the oft 
debated question as to the occurence of true Rhaetic beds there 
was taljcen up again, and though as much time as could be spared 
was given to the investigation, with the conclusion that the 
question must be answered in the negative, it is not pretended 
that the problem has been definitely solved, and the next time the 
Union visits the district, steps should be taken to open out a clear 
section and decide, once for all, the part played by the Market 
Weighton Axis, when the Liassic sea spread over the land. These 
are a few only, of the many problems that came under the con- 
sideration of the section during the year. They serve to indicate 
that there remains much to do. Work that will require patient 
and systematic investigation for many years before definite con- 
clusions can be arrived at. To that end special attention should 
be given at future excursions to the most pressing problems in 
each district visited.
