3- CieulogisLs proceed by 9-50- irain to Healey House Station : tlience, via 
Hall Hey Wood to the I'ault at Dolly Folly, then across the Meltham Valley to 
Houley Okl Wood, over the Millstone Grit Plateau to Wilshaw : thence, via Thick 
Hollins to Harden Moss. I.eader, Dr. T. W. Woodhead, K.L.S. 
BOOKS AND MAPS.— The area for investigation is included in Sheet 88 
of the One Inch (Jrdnance Map, which may be had geologically coloured. 
Annotated lists of the fauna and Hora, as complete as jjossible up to date of 
publication, are contained in Hobkirk's "History and Natural History of 
Huddersdeld." Later catalogues of the Lepidoptera (I'orritt and Mosley), Mollusca 
(Whiluham), &c., have api)eared in the "Trans, of the Huddersfield Nat. Soc." 
A catalogue of the larger Fungi (Clarke) was issued by the Botanical Society. 
There is a small pamphlet on the vertebrates (Moslcy) enumeialing all the species. 
The ecology of the area for investigation is dealt with in the " Fcology of 
Woodland Plants in the Neighbourhood of Huddcrsfield " (Dr. T. W. Woodhead, 
F.L.S.), and in the " Geographical Distribution of Vegetation in \'orkshire, Leeds 
and Halifax Disirict" (Smith and Moss). 
HEADQUARTERS.— Wood Cottage Hotel, Harden Moss, near Holmfirth. 
PERMISSION to visit their prt^perties has been kindly gianted by Messrs. 
Jonas Brook cS: Bros., Ltd., and Mr. George Hinchlifte. 
HARDEN CLOUGH AND WOODS.— Mr. W. E. L. Wattam writes:— 
Harden Clough is the largest valley within the Meltham area of the Holme \'alley 
drainage. The stream running through it arises on the moors in the vicinity 
of Harden Moss Farm at an altitude of 1,200 feet, its confluence with the river 
Holme being at Steps, Honley. The Cloifgh is a well-wooded picturesque valley 
commencing at Royd Edge, Meltham, emerging on to the moorland known as 
Harden Moss ; at which point, to the north, south and west, as far as the eye can 
reach, is one great stretch of moorland hilis with deep intervening valleys. To the 
east we look upon the limit of cultivation. The higher moors, rising to 1,909 feet 
at Black Hill, are covered with deep peat, through which numerous streams have 
cut their way. Immense areas are dominated by the cotton grasses with much 
birch buried at the base of the peal. The lower plateaux have a covering of 
shallow dry peat dominated by CaHuna and its associates. At the base of the 
Clough the wood is of a mixed type, Qiierciis sessilijlora, Ulnnis Montana^ and a 
sprinkling of Pinus sylvesiiis and Larix europ<Ta. Higher up the valley, just before 
entering upon the moor, is a small wood consisting almost entirely of birch. 
Harden Wood is also a Querciis sessiliflora wood with a considerable admixture of 
planted trees. The eastern portion of Thick Hollins Moor is a ty])ical Calluna 
heath ; tlie western portion, forming the banks of Snape Clough, is a grass heath 
with a considerable variety of typical moorland species. 
GEOLOGY. — The Geological section will be ofiicially represented. 
The rocks in the area to be investigated all belong to the Millstone Grit series, 
and may be divided into four distinct groups of sandstones and shales. First and 
uppermost is the rougii rock ; second, thin beds of I'higstones immediately beneath 
rough rock ; third, three beds of Sandstone, usually known as the Third Grits ; and 
fourth, the Kinder Scout Cirit. Some of the beds have been quarried and casts of 
Si miliaria and Stigtnaria are fairly common. 
The route chosen will illustrate the characteristic features of the Millstone 
Grits and slunv the relationship between geology and vegetation. From the top 
of Honley Moor a fnie vitiw of the plateau is obtained, also the grit capi)ed jje^ks 
of Wtst Nab and Shooters' Nab at either end of a synclinal hill. The junction 
between the (irits and Lower Coal Measi.res and the accompanx ing pliysiographical 
changes are also well seen.
