Abstract
THE assistance that photography can render in the laborious work connected with topographical surveys has been repeatedly insisted upon, and the recognition of the fact is being displayed in the construction of a class of instruments admirably adapted for use in the field. With the more convenient instruments that experience will suggest, and with the shortened methods that familiarity will supply, the employment of photography is likely to be still more general, though doubtless it will have to contend against a certain amount of prejudice in favour of older methods.
