A description, with discussion, of a new species of Ficus (F. inierglacialis) 

 from the Pleistocene deposits of the Kostenay Valley, British Columbia. 



The spécimen upon which the species is founded consists of a fruiting 

 brandi, along which the gigs are attaçhed in clnsiers. It is apparently, 

 closely allied to the gênerai type represented by the living West Indian 

 species F. populoides Warb. and F. populnea Wills. One plate shows 

 the spécimen natural size, the other a part of the some enlarged. The occur- 

 rence of 8 species of Ficus in thèse deposits is regarded as indicating a semi- 

 tropical interglacial climat e in the région.

The Silver Lake basin in Staten Island, New- York, was originally a valley 

 in the serpentinoid rock that was dammed at its outlet by morainal matërial. 

 It was recently drained, enlarged and converted into a réservoir. The geolo- 

 gical features revealed,and thecharacterof the végétation that took posession 

 of the drained basin form the subject of the paper. 



A feature of considérable interest was the « creeping » or slipping of the 

 silt along the margin of the basin, where crevasses were formed, due to con- 

 traction of the deposit on drying, after the water had been drained off. 



The illustrations include photograps showing certain of the crevasses, 



shrinkage cracks in the silt, a peat bed at one and of the basin, and several 



wiews showing the végétation that occupeid the margin and the inner area 



of the basin.

An illustrated description of a new genus and species of féru (Anomalo- 



filicites nionctrosus) from the Tertiary (Fort Union Formation) of Montana. 



The species is compared with the hetero morpbowe f ronds of the cultivated

included for comparison.

A description, with photographie illustration, of an artificial cave exca- 

 vated about the yaar 1790, in the serpentinoid rock of Staten Island, New- 

 York. The excavation was said to hâve been made in search of gold. The 

 jointing of the rock is a conspicuous feature which gives to the cave the 

 appearance of having been carefully eut or blocked ont.
