Having made enquiry about _Martini_'s Account of Sowing their Fields at _Ven-cheu_ with Oyster-shells, to make new ones grow; I was told that after they have taken out the Oysters, they sprinkle the Shells with Urine, then putting them into the Water again, there grows new Oysters on the foresaid Shells. _Martini_ says he could never find a _Latin_ Name for the _Fula Mogorin_ of the _Portuguese_, I'm sure it's the same with the _Syringa Arabica flore pleno albo in Parkinsone_. He says also, that the _Kieu-yeu_ or Tallow-tree bears a white Flower like a Cherry-tree; but all that I have seen here bears a spike of small yellow Flowers like the _julus_ of a _Salix_. The Bean, or _Mandarin_ Broth, so frequently mentioned in the _Dutch_ Embassy and other Authors, is only an Emulsion made of the Seed of _Sesamum_ and hot Water. Their chief Employments here are Fishing and Agriculture. In Fishing, they use several sorts of Nets and Lines as we do; but because they have large Banks of Mud in some Places, the Fisherman, to go more easily thereon, has contriv'd a small frame about 3 or 4 Foot long, not much larger than a Hen-trough, elevated a little at each end, in which he rests upon one Knee, leaning his Arms on a cross Stick, rais'd so high as his Breast, and putting out the other Foot often upon the Mud, he pushes forward his Frame thereon, and so carries himself along in it. As to their Agriculture, all their Fields (where any thing is planted) whether high or low, are made into such Plots as may retain the Water on them when they please. They Plow up their Ground with one Buffalo or one Cow. Where they are to Sow Rice, they prepare the Fields very well, by clearing it of all manner of Weeds, moistening to a Pulp, and smoothing it with a Frame drawn across; on which they Sow the Rice very thick and cover it only with Water for two or three Inches high, and when it has grown 6 or 8 Inches long, they pull it up by the Roots, and transplant it (by Tufts in a straight line) to Fields overflown with Water; and where a Field is subject to Weeds, when the Water drys up, they prevent their growth in over-turning the Mud with their Hands in the interstices where the Rice is planted. When they Sow Wheat, Barley, Pulse, and other Grains, they grub up some superficial Earth, Grass and Roots, and with some Straw they burn all together; this Earth being sifted fine, they mix with the Seed, which they Sow in holes made in a strait Line, and so grows up in Tufts as the Rice does; the Field being divided into Beds and harrowed over, both before and after the Seed is Sown: This makes them somewhat resemble Gardens. Altho' they meliorate their Fields, where they Sow Rice, only by letting the Water on them, yet for other Grains, where Ground requires it, they make use of Dung, Human Excrements, Ashes, _&c._ In watering their Fields here they use the same Instrument mention'd by _Martini_ in the Preface to
