I distinguish, he says, three different species of Pine Apple; the first and best has green leaves, garnished with fine prickles, fruit of which I have had seven inches high, and thirteen inches in circumference; this sort, if it is kept cool before it shows fruit, and then advances slowly by somewhat more heat, grows larger and more pointed than that which has been kept warmer and in a growing state during winter. The leaves of the second sort are larger and broader, of a darker green mixed with red; it does not produce fruit of so large a size, but its knobs are broader and larger, yet flatter; the unripe fruit being of a reddish brown, and when ripe of a deep yellow, with brownish yellow spots on the knobs; this sort has not so pleasant a taste as the first, which, when unripe, is of a darker green, and when ripe, with lighter yellow knobs, on which account I cultivate chiefly the following sort. This is called the Smooth Ananas, on account of its being without prickles, but the ends of the leaves grow longer, narrower, and more upright: the fruit is smaller. The Ananas cannot bear the cold of our winter, and must have in summer a more permanent warmth and less change in the winter than we commonly have in our climate; and must therefore not only be put during the winter into stoves, but even during the summer under glass frames, and the pots placed in a hot-bed of tan. However, it is with these plants, as it is with all others from a warmer climate; when they by degrees have been accustomed to our colder climate, they become more hardy, and can bear more cold and change of weather, and therefore produce better fruit than those which are sent to us from abroad and have been reared in a warmer country more congenial to their nature. It is therefore necessary that we should try to get plants that have already been accustomed to our country, by propagation from suckers for a number of years, for in that case they may be reared with very little trouble.
