The study of soil moisture is one of the many interesting subjects connected with the study of the soil. Perhaps in some cases the results of a single season may give valuable indications in certain lines, but it is the results of many years which give conclusions that mean much more to those interested in the subject. In commencing the work, the first part of which is presented to those interested in the subject, it was with the view that the work will be continued for some time to come, and as the work developes we hope that it will be the means of presenting some results that may be of value.
