360 DR. HONEYMAN’S WRITINGS—GILPIN. 
to his scientific pursuits, he resigned the more active duties of 
his Secretaryship, which were assumed by Mr. McKay and Mr. 
Macdonald,and he became Honorary and Corresponding Secretary. 
In 1871 and 1872 he read papers on the Geology of the rocks 
surrounding the Pictou coal field, in which he differed from the 
conclusions arrived at by Sir William Logan, and considered that 
they were an extension of the metamorphic Middle Silurian rocks 
of Irish and Fraser’s mountains. 
In 1873 he read a paper on the metamorphism of rocks in Nova 
Scotia and Cape Breton. In this interesting communication he 
dwelt upon the fact of the Lower Carboniferous Limestones not 
being altered when in contact with metamorphic precarbonifer- 
ous rocks, and upon the metamorphic character of all other lime- 
stones found in Nova Scotia. In this year he spent some time in 
examining the sections exposed by the cuttings of the Interco- 
lonial Railway in Halifax, Colchester, and Cumberland Counties, 
directing more particular attention to the Cobequid Mountains, 
in which he considered that he recognised extensions of his typical 
Arisaig series. 
A summer spent in New Brunswick gave him an opportunity 
of still further extending his Geological horizons, and the results 
were embodied in a paper read Nov. 9, 1874. At the Centennial 
Exhibition the Doctor was represented again by collections of 
fossils and minerals, and by eleven maps showing results of his 
labors since 1867. 
Hitherto, with the exception of his explorations on the Cobe- 
quids, Dr. Honeyman had confined his Geological work principally 
to the eastern part of the Province; but now, fortified by his 
experience, he began to extend his horizons into the Western 
Counties, and the country lying south of the Annapolis Valley 
was visited and carefully compared with the localities which he 
had. geologically speaking, mastered. His paper in Vol. 4 of the 
Transactions on the Superficial Geology of Nova Scotia, also 
marked a new departure, and his researches into the Glacial 
period in Nova Scotia henceforth occupied much of his time. 
The casual discovery on the shores of the Atlantic of a boulder 
undoubtedly derived from the Triassic trap of Blomidon or Parrs-
