of a man.  The sago, on being taken off the fire, is spread out to cool on large tables, after which it is fit to be packed in boxes, or put into bags for shipment; and is known in commerce under the name of “pearl sago.”  Thus the labor of fifteen or twenty men is required to do that which, with the aid of simple machinery, might be done much better by three or four laborers.  A water-wheel would both work a stirring machine and cause an inclined cylinder to revolve over a fire, for the purpose of drying the sago, in the manner used for corn, meal, and flour in America, or for roasting coffee and chicory in England.  But the Chinese have no idea of substituting artificial means, when manual ones are obtainable.

A considerable quantity of sago is exported from Singapore in the state of flour.  The whole quantity made and exported there exceeds, on the average, 2,500 tons annually.  The quantity shipped from this entrepot is shown by the annexed returns, nearly all of which was grown and manufactured in the settlement.  The estimated value for export is set down at 14s. per picul of 11/4 cwt.

THE BREAD-FRUIT TREE.

Artocarpus incisa.—­This tree is less cultivated than would be supposed from its useful properties.  In the West Indies and the Indian Islands, where it has been introduced from its native place, the South Sea Islands, it is held in very little consideration, the graminea, tuberous roots, and farinaceous plants being more easily and readily cultivated.  There are two or three varieties known in the Asiatic regions.  The properties of this tree are thus enumerated by Hooker:—­The fruit serves for food; clothes are made from the fibres of the inner bark; the wood is used for building houses and making boats; the male catkins are employed as tinder; the leaves for table cloths and for wrapping provisions in; and the viscid milky juice affords birdlime.

A. integrifoliais the Jack or Jacca, the fruit of which attains a large size, sometimes weighing 30 lbs., but is inferior in quality to the bread-fruit.
