THE RECLAIMED LAND OF THE HUMBER DISTRICT. 227 



i. — Reclaimed Areas. 



In searching for the aecidium on Glaux maritima, the host 

 plant was found inside the bank on Saltend Common, and at 

 the western end of Paull, where, in both cases, the salt 

 water only reaches when strong winds blow the spray over 

 the bank at spring tides. Near the searchlight station, east 

 of the battery, it grows inside the bank, on marshy ground 

 which is flooded at high tide through the Thorngumbald 

 Clough, and on Sunk Island it still grows on the shores of 

 Fisherman's Channel, a brackish lake on the enclosure of 

 1800, which is probably the nineteen acres of water referred 

 to in Kelly's "Directory" (1901). There are several similar 

 but smaller broads on Cherry Cob Sands, but I have not seen 

 Glaux there. The other host plant of the fungus, Scirpus 

 maritimus, is common in all the brackish ditches of Holder- 

 ness ; but except for a few plants at the head of Hedon 

 Haven, it does not occur outside the bank east of Hessle. 

 In place of it, we find Juncas gerardi on the salt marsh at 

 Welwick. 



On Cherry Cob Sands the tidal water frequently enters 

 the main drain so that, except in winter, the water contains 

 almost as much salt as that of the Humber. Ulva latissima 

 flourishes near the clough, and Chcetomorpha litorea and a 

 rigid Cladophora are abundant for the next two miles. [See 

 Trans. Hull S. and F.N. Soc. vol. 3]. Aster Tripolium and 

 Apium graveolens are common along the ditches. The 

 pastures on these areas have a characteristic appearance, 

 but their constituent grasses have not been noted : Carex 

 divisa generally occurs on those which have not been 

 " meadowed." 



Sunk Island is a place to be avoided by the botanical 

 collector. Even on the oldest enclosures he will find an 

 almost total absence of the commonest species, while promi- 

 nent notices forbid the removal of plants from the outer 

 bank and salt-marsh. The roadsides are bordered by a level, 

 lawn-like strip of grass on which only Bartsia odontites has 

 been noted, and the smaller ditches, owing to the thorough- 

 ness with which the drainage work has been performed, 

 grow grass only on sides and bottom alike. I have seen it 

 stated that the tidal water is occasionally allowed to enter 

 and fill the ditches, but have been unable to obtain any 

 confirmation of this rather improbable report. 



Glaux maritima, Spergularia marina, and Plantago Corono- 

 pus grow on the shores of Fisherman's Channel, and Aster
