Oil from tub Seeds of the Sun-Flower. 30^ 



" The perfon, who has raifed the greateft quantity of 

 the fun-flowers v/ith us, informs me, that one hundred 

 plants, fct about three feet diftance from each other, in 

 the fame manner Indian corn is commonly planted will 

 produce one bufhel of feed, without any other trouble, 

 than that of putting the feed into the ground, from which 

 he thinks one gallon of oil may be made. lobferved the 

 land, on which he planted the fun-flowers, to be of the 

 middling fort, and that he took no pains to hill them, or 

 even to loofen the ground about them, which from my 



own o!)fervation onfome planted in a neighbour's garden^ 

 I take to be of confiderablc ufe.

 quires much uouriniment, hilling does not feem fo i^ood 

 a method as that of fetting the feed or plant in a hole, and 

 when the plant is. about a yard high, to throw in the mould 



ro-md the flalk, fo that the furface of the ground may be 

 even about it. By an eftimate made it appears, that one

 not trouble you with it/" 



Tlie fuccels attending the trials already made, give the 



grcateil encouragement to profecute this ufeful difcovery. 

 And as the feeds of the fun-flower are at this time nearly 

 ripe, and in a proper ftate for extrading the oil from them, 

 it may be of fervice to lay thcfe fads before the public. 

 Such as may have an inclination to make trials on this 

 fubjed, and are not at prcfent furniflied with a fufficicnt 

 quantity of /eed for prcihag out an oil, may now fupply 

 themfelvcs with enough to plant for making experiments

For the information of thofe, who have both opportunity 

 and inclination to extend the enquiry, and render this a
