Excerpt from Transactions of the Canadian Society of Civil Engineers, 1906, Vol. 20 In writing papers, or discussions on papers, the use of the first person should be avoided. They should be legibly written on foolscap paper, on one side only, with a margin on the left side. Illustrations, when necessary, should be drawn on the dull side of tracing linen to as small a scale as is consistent with distinct ness. They should not be more than ten inches in height and in no case should any one figure exceed this height. Black ink only should be used, and all lines, lettering, etc must be clear and dis tinct. When necessary to illustrate a paper for reading, diagrams must be furnished. These must be bold. Distinct and clearly visible in detail for a distance of thirty feet. Papers which have been read before other Societies, or have been published, cannot be read at meetings of this Society. All communications must be forwarded to the Secretary of the Society from whom any further information may be obtained.
