Book Description
Excerpt from Mineral Land Surveying Oi the applications of plane surveying to the survey of mineral lands, no one is more representative or has been more greatly perfected in the West than the use of the sun to determine the bearing of a given line. For many years hearings were determined by the use of various solar attachments but of late years the method known as the direct observation seems to have almost entirely taken their place. While with great care any one of the several solar attachments on the market will give fair or even good results, they are all relatively expensive, fragile and with one exception, easily thrown out of adjustment. With the method known as the direct observation no attachment is needed to the ordinary transit provided with a vertical are or circle, preferably the latter, and no adjustment has to be considered other than those necessary to use in every transit in mineral land surveying. As the exact determination of the bearings of lines is probably more important in mineral land surveying than in perhaps any other branch of engineering, disregarding of course geodetic work, it will be taken up in detail.

Book Description
Excerpt from Types of British Vegetation: By Members of the General Committee for the Survey and Study of British Vegetation The work Of systematically surveying vegetation and recording the results on vegetation maps was begun in Scotland by the late Robert Smith in the Closing years of last century, and continued by his brother, 1 G. Smith, and various other workers. In 1904 these workers formed a committee, with the somewhat ponderous title of The Central Committee for the Survey and Study Of British Vegetation, to organise and facilitate work on these lines.
