fT^HIS is a work upon a hitherto neglected branch of bionomics, 

 -*- and as such we can cordially recommend it. It aims at showing 

 how the animals and plants inhabiting the sea-shore interact, and 

 how the environment influences their structure, functions, and 

 habits. It is well illustrated by a number of excellently chosen 

 photographs and drawings. The chapters that will be of most 

 interest to the geologist are those upon the physiography of the 

 sea-coast, and its plant and animal associations. The account of 

 the zoning on the rocky shore of Cardigan Bay is particularly 

 instructive, and the authors record the succession of nine species 

 of Trochidse and Littorinidae, and show how these are correlated 

 with different conditions of shore drainage and the type of rock 

 or soil from which it flows, as well as probably with the lime content 

 of the water. Among many other matters of interest investigated 

 by the authors and here described is the colonization of the Kiel 

 Canal by marine forms in a definite ecological succession.

Stratigraphy, Structure, and Possible Oil Eesources of the 

 Miocene Eocks op the Central Plain, Republic of Haiti. 

 By W. P. WooDRiNG. pp. 19, with a map. Washington, 1922. 

 nnHE United States Geological Survey has been lately engaged on 

 -*- behalf of the government of Haiti in carrying out a recon- 

 naissance survey of the territory of the Republic : the results of 

 this work are soon to appear, but the present section has been 

 published in advance on account of the oil possibilities of the region 

 described, which consists of folded Miocene strata, overlain by nearly 

 horizontal Pliocene. Descriptions are given of the. lithological 

 characters of the Miocene strata, which have a maximum thickness 

 of about 1,400 metres and are folded into a synclinorium striking 

 north-west-south-east. This series is called the Artibonite group, 

 and contains numerous shallow-water marine fossils, many still 

 undescribed. The map shows structures very favourable to oil 

 accumulation, and it is considered that exhaustive tests should be 

 carried out by drilling on the crests of the numerous minor anticlines. 



The Iron - Ore Resources of Europe. By Max Roesler. 

 Bulletin 706, U.S. Geo!. Survey. pp. 152, with xix plates 

 (maps) and 33 text-figures. Washington, 1921. 

 rpHIS Bulletin is avowedly a compilation, having been drawn up 

 -*- as part of the work of determining the extent and position of 

 foreign mineral deposits for the guidance of the American Peace 

 Commission. It is thus liable to the common defect of such com-
