7o A Midsummer Trip to the Tropics. could muster 20,000 infantry and 3000 horse ; there were 80,000 slaves; there were 1500 houses in Bridgetown and an immense number of shops ; and not less than two hundred ships were required to export the annual sugar crop alone. But Barbadoes differs also from most of the Antilles geologically ; and there can be no question that the nat- ure of its soil has considerably influenced the physical character of its inhabitants. Although Barbadoes is now known to be also of volcanic origin,—a fact which its low undulating surface could enable no unscientific observer to suppose,—it is superficially a calcareous for- mation; and the remarkable effect of limestone soil upon the bodily development of a people is not less marked in this latitude than elsewhere. In most of the Antill the white race degenerates and dwarfs under the influ- ence of climate and environment ; but the Barbadian créole — tall, muscular, large of bone — preserves and perpetuates in the tropics the strength and sturdiness of his English forefathers.

At its centre the trail is brightest ;— towards either edge it pales off cloudily,—curling like smoke of phosphorus. Great sharp lights burst up mo- mentarily through it like meteors. Weirder than this strange wake are the long slow fires that keep burning ¦¦¦¦¦¦¦¦¦¦^¦i
