For the full year 1890, the mean daily velocity of the wind 

 was 211.16 miles and the mean hourly velocity, 8.90 miles; for 

 the full year 1891, the corresponding velocities were respectively 

 214.82 miles and 8.95 miles; and for the full year 1892, 217.33 

 miles and 9.05 miles. 



The rain-fall in May, 1890, amounting to 10.13 inches was 

 larger than in any other month in twenty-four years. 



Conclusion. 



The foregoing summarized report, although embodying all the 

 data obtained by four years' observations, conveys but an imper- 

 fect idea of the daily requirments and nature of the work in 

 progress. 



By way of presenting its varied character more fully, as in 

 former years, I append the complete records for one month, 

 selecting for the current report the month of October 1892.
