which the first, extending thi'ough Paleozoic 

 time, properly belong to the genus Cordaites, 

 which is now fairly well known through its 

 fruit, flowers, leaves and stem structure. 

 The second group embraces plants of the 

 same general Araucarian type, but ranging 

 through the more recent formations com- 

 mencing with the Jurassic. The third 

 group is reserved under the old name of 

 Dadoxylon, for all those plants which can- 

 not be readily assigned to a given and well 

 recognized genus, and from which they 

 may be transferred as occasion requires. 



The present revision eliminates many of 

 the errors of the earlier descriptions, and 

 draws attention to important characters 

 hitherto overlooked. 



Quarry and WorlcsJioj) of the Stone Age in New 

 Brunstoick: By G. F. Matthew, A.M., 

 LL.D. 



The author describes a locality on the St. 

 John Eiver in New Brunswick, which ap- 

 pears to be the source of certain carnelian 

 weapons and implements that have been 

 found at various points on the River St. 

 John. The locality is at Washadunoak 

 Lake, in Queen's County. 



Notes on the Physical Feature and Geology of 

 the Area between the Lower Ottaioa and the 

 St. Laivre7ice Rivers : By E..W. Ells, LL. D. 

 This paper discusses some of the points 

 relating to denudation which have been 

 furnished by a series of borings recently 

 made in the area south of the Ottawa 

 River. From these the presence of a pre- 

 glacial channel of that river of considerable 

 depth is clearly shown following in part the 

 lines of the Canada Atlantic and the Cana- 

 dian Pacific railways. The thickness of the 

 several formations of the Palseozoic forma- 

 tions in this part of the basin is also con- 

 sidered, and the presence of several impor- 

 tant faults and anticlinals which traverse 

 the district is considered, and their pi'ob- 

 able location given. These features are of 



interest at the present time in view of the 

 inquiries recently made as to the possible 

 occurrence of natural gas and oil in certain 

 portions of this basin. 



Tlie PalcEOzoic Formations of Eastern Canada : 

 By Heney M. Ami, M.A., D.Sc, F.G.S., 

 of the Geological Survey of Canada. 

 Communicated by Dr. Fletcher. 

 Considerable discussion has arisen of late 

 i-egarding the place which many of the geo- 

 logical formations of Eastern Canada occupy 

 in the column of the Palaeozoic period. 

 There is much confusion in the variety and 

 use of many geological, geographical and 

 other terms in describing or defining vari- 

 ous formations in this portion of Canada. 



An attempt is made to present a simple 

 and at the same time comprehensive classi- 

 fication of the various strata which com- 

 pose the earth's crust and belong to the 

 Paljeozoic period. Many interesting ques- 

 tions in the nomenclature of Canadian rock 

 formations are discussed and such names 

 introduced as will serve to designate many 

 hitherto unrecognized or undifferentiated 

 formations in Canada. 



Some Recent Work in Economic Entomology. 



Presidential Address of Section : By the 



Eev. De. Bethune. 



In his presidential address Dr. Bethune 

 presented a most comprehensive and practi- 

 cal treatise giving historical references and 

 data bearing upon researches in economic 

 entomology in Canada. From the days of 

 small beginnings to the present specific leg- 

 islation, restricting the encroaches and rav- 

 ages of insect pests, as well as encouraging 

 the application of every scientific fact of 

 value to man in the department of agricul- 

 tural pursuits, the author points out what 

 has been, and what is, being done.
