I think the best answer to that question is to read a summary of the contract that is entered into with those who operate:
1. A rental of $5 an acre is paid where the plots do not exceed one-quarter acre each. Usually this plot area does not exceed one acre. On this class of work the supervisor puts in all the crop and harvests it.
2. Where the plots are smaller than %o acre each, the operator receives $25 an acre compensation for the loss of the crop on such small areas.
3. A rental of $3 an acre is paid where the blocks of land do not exceed three acres. The total area of such stations is frequently from twelve to fourteen acres. The operator handles all of this crop.
4. A rental of $1 an acre is paid for the district experiment substations in the P.F.R.A. area in the prairie provinces. Large scale work is undertaken with strip farming, cover crops and surface tillage in connection with soil drifting control.
On some of these district experiment substations small plot experiments are also conducted.
5. Special contracts have been made in connection with special work such as with cranberries, raspberries, hops and irrigation. None of these exceed $150 each. For certain operators along the line of the Hudson Bay railway an annual payment of $5 per acre is made while some of these operators receive no payment whatever.
For pasture experiments no rental is paid but the fertilizer is supplied free.
6. Total maximum payments to any operator in eastern Canada is confined to less than $100.
In western Canada the limit is confined to below $200 for illustration station operators, while for operators of district experimental sub-stations the limit varies, being $1 an acre up to one section of land, plus payments for small experimental plots at the rates set for illustration station compensation. The upper limit, therefore, would not exceed $800 and usually is considerably less.
