the rate it is going it will take only
100000 years for all the land to slide

According to the British consul at
Nice, a method of detecting the admiy-
ture of other oils with the genuine olive

changes color, becoming reddish or
brown, instead of retaining the green
ish-gold of the pure olive-oil. The in
ventor of this process has also applied
it with success to the detection of mar
garine in butter, and much attention is
