Birds (Rapid Flight Of). A vulture can fly at the rate of 150 miles an hour. Observations made on the coast of Labrador convinced Major Cartwright that wild geese could travel at the rate of 90 miles an hour. The common crow can fly 25 miles; and swallows, according to Spallanzi, 92 miles an hour. It is said that a falcon was discovered at Malta twenty-four hours after the departure of Henry IV. from Fontainebleau. If true, this bird must have flown for 24 hours at the rate of 57 miles an hour, not allowing him to rest a moment during the whole time.
