382 REPORT OF THE ACTING METEOROLOGIST OF THE 
Wind REcorD. 
The record of direction of the wind has been kept through the 
year and is given below. The record of distance of movement has 
not been satisfactory until very recently. Changes in the appar- 
atus designed to give this record have made it possible to get the 
miles of movement in a given time. This apparatus is on the 
principle of the Robinson anemometer. The recording part 
depends on the vertical movement of a pencil on paper drawn 
daterally by clock-work, one inch per hour. The pencil should 
move about three-sixteenths of one inch for every ten thousand 
revolutions of the apparatus and each revolution is calculated to 
denote the passage of very nearly twenty-one feet of air. 
Following is the record of direction in detail for one year: 
Combining the summaries for each month for the nine months 
recorded in 1888* shows the prevailing winds to have been from 
a westerly direction. 
The same summary for the first ten months of 1889 shows the 
prevailing winds to have been from the same (westerly) direction, 
as shown in the table below. 



*See Seventh Ann. Rep., pp. 174-5, for seven months’ record.
