horse latitudes, 3.
latitudes or Subtropical High are subtropical latitudes between 30
and 35 degrees
both north and south, characterized
by light winds and hot, dry weather, caused by descending air. The belt
in the Northern Hemisphere is sometimes called the “calms of Cancer” and
in the Southern Hemisphere it is called the “calms of Capricorn”.
The phrase's etymology is uncertain. Supposedly, the term originates
from ships traveling to the New World that were often stranded in this
region and forced to kill onboard horses in order to preserve precious
water supplies, or for their meat and blood, but this may be apocryphal.
