bright again in the regions which had been inundated with rain; a relatively dry period commences in the spring, and lasts until the sun has
again crossed the equator toward the southern lands. This alternation of
the seasons is accomplished with great regularity on the coasts of California and Oregon, at Madeira, in Algeria, and on the coasts of Portugal. It
is thus that at Lisbon only 0*16 inch of rain falls in July, while in December the total precipitation is 4*9 inches. At Naples, and even at Rome,
summer droughts rarely disturbed by showers follow the winter rains.
As to the region of the spring and autumn rains, it ought to comprise
the countries over which the returning trade-winds blow at the epoch
when the sun is at the zenith ofthe equator; this is the equinoctial period
of March or September. In certain countries in the south of Europe, and
especially in Provence, we observe, in fact, that the rains are most abundant in spring and autumn. Even in Alsace the greatest quantity of rain
falls in spring, and flows into the tributaries of the Rhine, as shown in
figure on opposite page, borrowed from a work of M. Charles Grad;* but,
with some exceptions, the maximum of autumn is generally the highest of
the two, and that of the spring ends by disappearing entirely in a north-
