Deposits containing Fossil Plants. 57 
A is Recent or Neolithic C, from the occurrence of 
Salix herbacea and Apus glacialis, is classed as Late 
Glacial. D and F are provisionally classed with C, but 
may belong to a milder, Interglacial, period. These 
deposits, and those found at Close y Garey, occupy 
silted-up hollows in the glacial gravel. It is not yet clear 
whether the poverty of the flora, and the entire absence 
thus far of remains of dry-soil plants, is due to the 
barren water-logged character of the gravel-flat, or is 
characteristic of the flora of the Isle of Man at these 
periods.

The newest of these, about 4 feet below mean tide, 
yielded a polished Neolithic implement and also, according 
to Mr. Storrie, logs of Willow, Pine, and Oak. An 
associated shell-marl was full of freshwater shells and 
seeds of :— 
Rumex crispus. Potamogeton. 
Atriplex. Najas marina. 
Salix (leaves). Chara, 2 species. 
Najas marina is now confined to east Norfolk. 
The second peat, or land-surface, is composed mainly 
of sedges (Scirpus maritimus) and lies about 9 feet below 
mean-tide level. 
The third peat is composed of large timber and matted 
Sallow and Reed, with seeds of Valeriana officinalis and 
Carex. It lies 20 feet below Ordnance Datum, but shows 
no sign of the influence of salt water. 
The fourth peat is a true submerged land-surface, full
