side by side and should not be separated from one another
or the rest of the field. One plot, No. I, plow in well-rot-
ted stable manure at the rate of sixteen large loads per
acre - one load for every ten rods. Plot No. 2, which is
to be the middle plot, has no manure of any kind upon it.
When the cane on plot No. 3, is three or four inches high,
apply plaster to the hills or rows to the amount of one hun-
dred and sixty pounds per acre, or ten pounds for every ten
rods. The cane is to be planted and cultivated in the same
manner as the rest of the field.. If possible, weigh the cane
of each plot separately when ready for the mill. Boil the
juice to a syrup weighing eleven and a half pounds per
gallon, and determine accurately the yvield of each plot.
Save a sample of syrup from each plot for comparison.
   Report to the department upon the following points:
   1. Amount of ground in each plot.
   2. Character of soil-clay, loam, sand, etc.
   3. Is soil naturally rich or poor?
   4. Number of years the field has been in cultivation.
   5. Crops grown on field previous year.
   G. Wnether or not thb, field was manured the previous year.
   7. Method of planting cane-in drills or hills.
   8. Time of planting.
   9. Time of ripening.
   10. When manufactured.
   11. Yield of syrup from each plot.
   12. Character of syrup from each plot as to color, clearness,
 and flavor.
   In addition to the above, give any facts of interest in con-
 nection with the experiment, making the report as full as
 possible.
   All reports should be sent in by the first of December,
 and the samples of syrup from each plat should be pre-
 served until some method is devised for collecting and
 comparing them.
                         CONCLUSION.
   In concluding this most hastily written circular, I take
 occasion to urge upon those interested, to send in any facts
 they may possess that will help us along in the work. All
 letters of inquiry will receive attention. I shall send these
 circulars to everv cane grower whose name I now have on
 my list, but this is very incomplete; and I ask those who
 may receive it to send in the names of neighbors who are
 interested and help to scatter it over the state. All facts
 worthy of public attention during the growing and manu-
 facturing season will be announced in the WISCONSIN
 FARMER, publshed at Fond du Lac.
