SUNSHINE. 
§70. Instead of giving the sunshine throughout the 
year by tables, an attempt is made in figure 19 to show 
graphically the amount through the year, showing not 
only the amount received each day, but the time when 
it occurs, which would be impossible to show clearly in a 
table. 
A space is given for each day. The occurrence of sun- 
shine is shown by the heavy line and the length of the line 
shows the duration of the sunshine, which can be deter- 
mined by comparing with the scale. Cloudiness or the 
absence of sunshine is shown by the line being blank. 
The upper line in the diagram represents the time of 
sunrise, — when, on a clear day, sunshine should begin, — the 
lower line, sunset. The distance of these lines from the 
middle line, representing noon, Is proportional to the length 
of the forenoon and of the afternoon respectively. Allowance 
has been made for the shortening of the afternoon due to the 
presence of mountains on the western horizon, d'he two 
other lines represent 9 a. m. and 3 p. m., and are placed 
three hours distant from the middle or noon line, d'he time 
is, therefore, counted in apparent or sun time, without al- 
lowance for the equation of time. 
If, therefore, the sun shines from its rising to its setting.
