These devouring Ants showed themselves about the year 1760 in Barbados, and caused such devastations that, in the words of Dr. Coke, “it was deliberated whether that island, formerly so flourishing, should not be deserted.” In 1763, Martinique was visited by these devastating hordes; and about the year 1770 they made their appearance in the island of Granada. Barbados, Granada, and Martinique suffered more than any other islands from this plague. Granada especially was reduced to a state of the most deplorable desolation; for, it is said, their numbers there were so immense that they covered the roads for many miles together; and so crowded were they in many places that the impressions made by the feet of horses, which traveled over them, would remain visible but for a moment or two, for they were almost instantly filled up by the surrounding swarms. Mr. Schomburgk assures us that calves, pigs, and chickens, when in a helpless state, were attacked by such large numbers of these Ants that they perished, and were soon reduced to skeletons when not timely assisted. It is asserted by Dr. Coke that the greatest precaution was requisite to prevent their attacks on men who were afflicted with sores, on women who were confined, and on children that were unable to assist themselves. Mr. Castle, from his own observation, states that even burning coals laid in their way, were extinguished by the amazing numbers which rushed upon them. Notwithstanding the myriads that were destroyed by fire, water, poison, and other means, the devastations continued to such an alarming extent, that in 1776 the government of Martinique offered a reward of a million of their currency for a remedy against this plague; and the legislature of Granada offered £20,000 for the same object; but all attempts proved ineffectual until the hurricane in 1780 effected what human power had been unable to accomplish. In 1814, the Ants again made their appearance in the island of Barbados, doing considerable injury; but happily they did not continue long.[579]
