California Orange 
Grove 
The picture shows 
a typical orange grove, 
such as may be seen either 
in southern or in north- 
ern California. Curiously 
enough the fruit comes to 
maturity in the northern 
pari of the state, or at 
least in certain regions of 
the northern part, earlier 
than in southern Califor- 
nia. The anomaly is ex- 
plained as due to ocean 
currents, which modify the 
temperature with curious 
and unexpected results. In 
a recent year when oranges 
were destroyed by frost 
in the southern part of 
California, those in the 
northern part of the state 
escaped because they had 
already been picked 
for the market,
