And at Clifton-on-Bowmont, 121 



These conclusions are confirmed loj an experiment I 

 made in 1901 in the Big Haugh field (vide Appendix III.), 

 by which I lost about the rent of the land by adding 

 dung and kainit to my ploughed-in turf. The manured 

 section gave 15 tons of potatoes an acre, at an estimated 

 cost for manure of £2 10s. ; the turf-manured section 

 gave 14 tons 6 cwt., estimating the potatoes at £2 per 

 ton, the result was that we lost £1 2s., or about the rent 

 of the land, from having used manures in addition to 

 turf. This year (1904), which I am told is an inferior 

 potato year as compared with last year, the potatoes, 

 grown on Hayhope Shank Field East, show a decline to 

 12 tons 18 cwt. 4 lbs. on the manured section, and 12 tons 

 7 cwt. 1 lb. where the turf alone was relied on. It is 

 interesting to note that these results had been obtained 

 under much more unfavourable circumstances, as, from 

 certain requirements on the farm, the rotation system an 

 the case of this field was altered to oats out of 

 grass, turnips, barley, and turnips, part of the field 

 this year being allotted to potatoes, so that they 

 were preceded by a cereal crop, then a turnip crop, and 

 then by another cereal crop. As neither of the two cereal 

 crops had any manure, and the turnips some artificials 

 only, the crop of potatoes, may be considered to be the 

 most satisfactory evidence of the great value of turf as 

 manure, and especially of its lasting effects. It will be 

 interesting to observe how, on the potato section of 

 Hayhope Shank field, the grass will compare with that 

 on the section in turnips. As yet, no difference can be 

 perceived in the Big Haugh field between the grass after 

 potatoes and the grass after turnips. But it must be 

 remembered that the Big Haugh potatoes were taken 

 out of grass, while those of Hayhope Shank were the 

 fourth crop of the series, which no doubt accounts 

 partially for the shortness of the crop. A fifth crop, a 

 cereal one, will be taken next year, when the grass seeds 

 will be sown along with it, and this crop will be taken 

 without manure, so that the system will be put to a very
