Abstract

The construction and use of the Hose U-tube Level as designed by Mr. J. P. Fallon was described by him in the Sept.-Oct. 1952 issue of the Journal of Agriculture. Thus he made available to farmers the means of making a simple home-made levelling device which would give accurate and reliable results, enabling them to tackle contour surveying with confidence.

Various improvements have been made to Mr. Fallon's original design and the purpose of this article is to describe the construction and use of the most improved type of hose level.

The first section of this article was written by Mr. J. E. Watson, who did much to incorporate the many suggested improvements on the old level into the efficient and versatile level in its present form.

The second section was written by Mr. B. a'B. Marsh, who has used the level consistently under practical conditions to assess its uses and limitations as a surveying instrument and to work out a convenient method of use.

G. H. BURVILL, Commissioner of Soil Conservation
