its organic contents. The fossils, he states, "have a 

 decided generic agreement with the fossils of the Triassic 

 period". Gesner [8] also, in 1843 included the Windsor 

 in his New Red Sandstone division. Murchison [10], 

 in the same year, suggested a Permian correlation on the 

 basis of the fossil determinations of de Verneuil, Keyserling 

 and himself, but Lyell [7] shortly afterward overthrew 

 previous opinions by his evidence in favour of the Lower 

 Carboniferous age of the series, including in his "Travels" 

 a short list of the characteristic species of fossils. 



It remained for Dawson [3, pp. 278-314] in 1868, to 

 present the most comprehensive description and illustra- 

 tion of the Windsor fauna, finding many of the species 

 closely allied with species of the Mountain Limestone 

 of England, while de Koninck confirmed his views and 

 correlated the formation with the Carboniferous Limestone 

 of Vise in Belgium. Davidson [18] had previously 



described many of the brachiopods submitted to him by 

 Billings. How and especially Hartt have also contributed 

 to our knowledge of this fauna. 



Little work has since been done in adding to the faunal 

 relations stated by Dawson. Schuchert [19], after several 

 visits to the Windsor locality, stated in 1910 that "the 

 oldest fauna of this series at Windsor includes but few 

 species, and these remind one of Kinderhook time. In 

 the higher dolomites at Windsor a rich fauna appears 

 that is very different from that in any American Mississippic 

 horizon, and as it is also unlike those of Europe it is dim- 

 cult to correlate. Seemingly it is of Keokuk time, yet 

 it may be somewhat younger as Lithostrotion is reported 

 at Pictou, which is not far from Windsor." This view 

 finds further corroboration in Beede's [20] description 

 of the same fauna found by John M. Clarke in the Magdalen 

 islands. 



Industrial Notes. 



Gypsum has been the only mineral of industrial 

 importance mined in the Windsor district. The great 

 quantities and accessibility of this rock to navigable waters 

 gave an early impetus to its exploitation, and quarrying 

 operations have been carried on in the vicinuy of Windsor 

 for over a hundred years. In Haliburton's "History of 

 Nova Scotia", 1829, it is stated that nearly 100,000 tons 

 were annually shipped to the United States, where it was
