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 his Atlas, being all of Wood, and the contrivance the same with that of a Chain-Pump.
Their method in making of Salt is this: All the Shores here being Mud, instead of Sand, in the Summer Season they pare off the superficial Earth, which has been overflown with the Salt Water, and lay it up in heaps for use; when they are to use it they dry it in the Sun, rubbing it small; then digging a Pit, they cover the bottom thereof with Straw, at which thro' the side of the Pit they pass a hollow Cane, that leads into a Jar, which stands below the level of the Pits bottom; they fill the Pit almost full with the foresaid Earth, and pour Salt Water thereon, till it be covered two or three Inches with Water, which drains through, into the foresaid Jar, and is afterwards boil'd into Salt.
Had I not found the Printed News Papers last Year take notice of a singular Root brought from China by F. Fontaney, I should not have told you, that I have seen one since I came here call'd Hu-chu-u (which I take to be the same) whereto they ascribe wonderful Properties of prolonging Life, and turning grey Hairs into black, by drinking its Infusion for some time, insomuch that they say it's to be had in value from 10 Tael to 1000 or 2000 a single Root; for the larger it is, the more is its value and efficacy: Which is too much Money here to try the Experiment. You have it mention'd in Cleyer's Medicina Sinica No. 84. under the Name of Ho-xcu-u, according to the Portugal Spelling: It's likewise painted in the 27th Table of those Plants Mr. Petiver had of me. If you'll have the Story of its Discovery, which I will not warrant for Gospel, it runs thus. Upon a time a certain Person going a Simpling among the Mountains, fell by accident into such a steep Valley that he could by no means get out of it again; whereupon looking about for something to sustain his Life; in this melancholy condition, he espy'd this Root, of which he made Tryal; and found that in eating thereof, it serv'd him both for Provisions and Clothing, by keeping his Body in such a temperature, that the Injuries of the Weather had no influence upon him during his stay there, which was some hundreds of Years; till at last an Earthquake happen'd in that place, whereby the Mountains were rent, and he found a passage out to his House, from whence he had been so long absent: But the many alterations that came to pass there in such a space of time, would not permit them to give Credit to his Story; till consulting the Annals of their Family, which gave an Account of one of them lost at that time, they were confirm'd in the truth of his Relation. And so much for this.
