The Nanaimo Field was examiaed by Dr. Hector, ia 1859. He suc- 

 ceeded ia working out a section of the region, which is practically as fol- 

 lows : * 



1. Purple clays not measured. 



2. Conglomerate and sandstone 500 to 600 ft. 



3. Coed, "Douglas" seam. 3 ft. 6 in. 



4. Conglomerate 60 ft. 



5. Ooal, "Newcastle" seam 6ft. 



6. Sandstone ~| 



7. Conglomerate [ 



8. Green sandstone. \ about 400 ft. 



9. Tufaceous rock I 



Greenstone conglomerate J 



10 



11. larneous rocks. 



No. 8, is richly fossiliferous, containing as determined by Mr. Ethe- 

 ridge, Trigonia Emoryi, CytTierea Leonensis, Exogyra two species. Area 

 three species, Ostrea two species. 



The sandstone of No. 3, contains a thin coal, accompanied by plant- 

 bearing shales. Yew-like fronds occur in the arenaceous shales associa- 

 ted with the larger coals. 



No. 1 is a thick mass of shale somewhat variegated in color and con- 

 taining great numbers of "nodules or septaria " enclosing fossils. From 

 these nodules there were obtained liioceramus Grispii, (Conrad), I. Tex- 

 amcs, I. Nebrascensis, 1. unduloplicatus, 1. confertim-annulatus, I. myti- 

 loides, Baculites compressus, Baculites two species undt.. Ammonites 

 geniculatus, Ammonites two species undt. 



Mr. Brown'sf observations at Nanaimo, coniirm those of Dr. Hector. 

 In the shales accompanying the coals, he obtained great numbers of leaf 

 impressions, both mono- and di-cotyledonous ; while from the associated 

 sandstones, he procured various species of Ammonites, Baculites, Inoce- 

 ramus, Exogyra, Ostrea, Pecten, Area, Trigonia, (Jytherea, Psammobia, 

 Tellina, Mactra, Natica, Bostellaria, etc. 



In the northwestern or Comox field, he found a grouping of conglom- 

 erates, sandstones, fire-clays, and coals similar to that observed in the 

 vicinity of Nanaimo. Throughout the series there are fossiliferous 

 beds. Dicotyledonous plants are most frequent among the leaf impres- 

 sions, while among the animal remains there occur Ammonites, Baculites, 

 Pectunculus, Plagiostoma, Inoceramus, Trigonia, Hippurites, Astarte, 

 Natica, and Paludina. 



Mr. Richardson^ examined the Nanaimo field in 1871, and the Comox
