Pressure is not employed. Peat prepared in this way is sold at 4 dols. per ton in Montreal, and has been used advantageously for the pro- duction of steam and in domestic fires. In Ireland and in Scotland attempts have been made on a large scale to use peat as a source of tar, coal-oil, and other products. In some cases the results have been profitable, in others the reverse. This appears to have depended partly on the processes em- ployed, and partly on the quality of the material. Persons desirous of making further inquiry on this subject will find additional details in Sir W. E. Logan's Report on the Geology of Canada, 1863, and in a paper by Dr Hunt in the Canadian Naturalist for December 1864. (C.)—CoNE-iN-CoNE Concretions, Every field-geologist is familiar with various forms of concretions, as of clay-ironstone, flint or chert and carbonate of lime, which occur in clays and similar beds, or in limestones. They are in general attributed to the mutual attraction of particles diff"used through masses of sediment, and aggregating themselves around solid bodies as nuclei, or flowing into cavities of fossils and other places of least resistance. Such nodular arrangements are especially abundant in the underclays and other clay beds of the Coal measures, where the carbonate of iron formed by the action of decaying vegetable substances on the oxide of iron present in the sediment, has shown a singular aptitude for assuming such structures, and the nodules and nodular sheets of ironstone often contain fossils of much interest.
