Properties and Uses. — Of all orders of plants there is none,

 as regards their dietetical and economic applications, as the 

 Palm Order. These plants supply him with sugar, starch, oil, 

 wax, wine, resin, astringent matters, and also edible fruits and 

 seeds. Their terminal leaf -buds, when boiled, are eaten as a 

 vegetable. Their leaves are applied in various ways, as for 

 thatching, materials for writing upon, and in the manufacture 

 of hats, matting, &c. ; their wood is applied to many useful pm-- 

 poses ; the fibres of their petioles and fruits supply materials 

 for cordage, cloth, and various other textile fabrics ; and the 

 hard albumen of then- seeds is applicable in many ways.
