REPORT OF PROGRESS OF THE DIVISION OF 
HYDROGRAPHY FOR 1893 AND 1894. 
By F. H. Newell. 
INTRODUCTION. 
This bulletin contains the results of observations and measurements 
made by the Division of Hydrography during the calendar years 1893 
and 1894, together with similar facts obtained by persons or officials 
cooperating with the Survey or conducting related lines of investigation. 
It has not been customary to publish results until the computations have 
been fully worked up and the matter has been put into the most concise 
form possible for insertion in one of the papers accompanying the Annual 
Report; but experience has shown the desirability of printing at as 
early date as possible much of the original data regarding the location 
of the river stations and daily observations, as these are becoming to 
be matters of importance to individuals and communities in different 
parts of the country. In the past all facts of this kind have been fur- 
nished by letter to persons requesting them, but a time has been reached 
when it seems economical and advisable to present these matters in 
form accessible to all persons. It is proposed, therefore, to publish in 
bulletin form, without illustrations, the data obtained during each field 
season, reserving the more condensed general statements and the results 
of final computations, as before, for the Annual Report of the Survey, 
wherein they will be presented, as far as possible, graphically, by means 
of maps and diagrams. In one of the annual reports succeeding this 
bulletin will be given a resume of some of the data herewith presented. 
This will be the sixth paper of the series. 1 
The field seasons for the years 1893 and 1894 marked the time of 
greatest depression for the Division of Hydrography and the begin- 
ning of a period of renewed activity. During 1893 and the earlier
