342 ' On the Cultivation of the Poppy. 
Expenses, Produce, and Profits.—Concerning these arti- 
cles it will be necessary to be particular, though it is some- 
what difficult, from a difference in the current coins, mea- 
sures, &c. JI shall state the result of experiments made on 
300 roeden *, about one acre of a sandy soil, and 300 roeden 
of a heavy peat, made by a claimant named S. N. Van Eys. 
The peat land being low and humid, he was obliged to make 
deep trenches between the beds. The harvest on this soil 
was later, the poppy heads were not so dry when gathered, 
and they shrunk considerably in drying. There was so small 
a difference in the quantity of seed from these different soils, 
that no important preference could be given. The sand 
ground yielded in this instance rather less than the peat land. 
As the quality of the seeds appeared perfectly similar, he 
mixed the whole produce together, when he sent them to 
the oil mills. 
The produce of the sand ground rather exceeded 13 sacks, 
that of the veen or peat land was about 12 sacks; together, 
they made 25 sacks 1 bushel of seed. These yielded of oil 
in the following proportions : 
Minglest. Cakes. 
23 sacks which were pressed cold gave 271 834 
2 sacks warmed - - - 29 56 
834 cakes, warmed and pressed, gave 73 
—— 
Total oil 373 800 
Cakes diminished in a second pressure to 
726 - - - - minus 108 
Total of cakes 782 
Mr. Van Eys remarks, that poppy oil, of a very inferior 
quality, is sold retail at one guilder, or 15. 10d. per mingle, 
or quart, and that mixed with olive oil at a much higher price. 
However, he estimates the cold-drawn at 16d. only, and 
* The English statute acre is 160 square perches; and the Dutch merge, 
consisting of 600 roeden, is equal to 800 square perches: so that the differ- 
ence between a Dutch morge and two acres, is as 300 to 320, the former 
being only twenty perches less than two acres. 
+ A mingle is about two pints.
