branches, with short obtuse leaves. Dutrichum homomallum 
was gathered by Mr. H. E. Johnson, and Mr. J. C. Wilson 
directed attention to Catharinea crispa and Tetraphis Browni- 
ana, the former in great profusion, with male inflorescence. Al- 
together forty-nine species of mosses and liverworts were noted. 
FLOWERING PLANTS AND FERNS.—-Miss C. E. Andrews 
writes :—The botanical section was well represented. The 
rainfall had refreshed all vegetation, and the floral charms of 
the valley were seen practically to their full perfection. 
Undoubtedly the most interesting plant was Pyrola media. 
The noteworthy plants of the swamp areas were Lychnis flos- 
cuculi, Valeriana officinalis, Myosotis palustris, Cinanthe 
crocata, Cardamine amara, Glyceria fluitans, Carex ovalis, 
C. sylvatica, C. binervis, and Equisetum palustre. The cut- 
leaved form angustifolium of Heracleum sphondylium, often 
met with in gritstone valleys, was also noted, as was also 
Hypericum pulchrum. Unfortunately the herbage of the 
field where rare species ot orchids were known to occur had 
been cut down, and the only species seen were Hahenaria 
virescens Druce, and O. maculata. On the steep crags near 
the Falls the countless blossoms of Crepis paludosa and Lactuca 
muralis made a pretty picture. Amongst the trees was 
Prunus Padus in fruit. The uncultivated upland pastures 
yielded a characteristic heath association of plants, Evica 
tetralix being not uncommon. The wealth of ferns is one of 
the charms of the valley. Many species were seen, amongst 
them being fine examples of Lastrea oreopteris, L. dilatata, L. 
spinulosa, L. filix-mas, with its scaly rachis form paleacea, 
and Athyrium Filix-femina. Mr. Burrell found a frond of the 
latter fern which had developed two distinct branches. Poly- 
podium vulgare and Ophioglossum vulgatum were also listed. 
GEOLOGY.—Mr. J. Henry Greenwood reports :—The geolo- 
gists took the opportunity of examining the lower beds of 
Kinderscout grits and the upper beds of the Yoredales or 
Pendlesides. These beds form the most prominent physical 
feature of the district from the bottom of the Calder Valley, 
320 feet, to the 800 feet line. Above these the alternating 
bands of grits and shales of the middle grit series, with a thin 
seam of coal and ganister, at 1,000 feet, cap the hills to the 
east and south-east. A good section of the Kinder grits was 
seen in Nutclough. They were found to be a very coarse ~ 
grained sandstone containing a large quantity of quartz 
pebbles, and also a number of fairly large nodules. Throughout 
the district on this particular horizon these nodular concretions 
are very abundant. They were also examined at the quarries 
in Pecket Wood. 
In Crimsworth Dene the effect of grit rocks resting on 
shale beds in a narrow valley was noticed. Huge blocks of
