the field mentioned (p. 73), excepting on a low-lying part round the 
knoll, which was bad with “ Tulip-root,”—to which part a less quantity 
of manure was given. 
Mr. Elder further added :— 
“ Regarding the prevention of this pest, I would suggest the following 
precautions, as the result of my experiments and observations this and 
past seasons :— 
“ 1st. The land to be maintained, in as high a state of fertility as 
possible, with farmyard or town manure. 
“ 2nd. Alternate with Barley or Wheat when practicable. 
“ 3rd. Sow along with the Oats a manure containing phosphates, 
ammonia, and potash (the two latter in considerable quantity). 
“ Note .—The plant appears to require more potash in its early 
stages than the majority of soils can readily supply it with, where the 
land is constantly under tillage : from one to two cwts. per acre of 
sulphate of potash, applied when sowing the Oats, will be found to 
keep the plant green and healthy, when without the potash it would 
become yellow after the supply of food from the grain was exhausted. 
This is the stage of growth when the Anguillulidce make their attack, 
and, if the plant is carried on through this stage in a healthy growth, 
comparatively little danger may be apprehended afterwards. The 
ammonia would now step in, and carry on the plant during the 
remainder of its growth, the phosphates improving the grain. 
“ The above is not only theory, but it is the actual results of my 
experimental plots this season, as far as it has gone. 
“ 4th. I observe this year that, wherever the broad-wheeled carts 
have crossed the Oat-fields, in carting out grain or manure or carting 
off stones, the plants in the track are extra strong and healthy, 
showing that perhaps my soil is too loose for Oats, and that the crop 
would be much healthier if rolled with a heavy stone roller, or some 
other contrivance, to consolidate the land. 
“ 5th. Variety of Oats appears to have a marked effect. A field of 
* Sandy ’ Oat is a fine level crop, Two bushels of . . . * Oat sown 
alongside, to finish the field, getting the same manure, &c., is very bad 
with ‘ Tulip-root.’ 
“ Hamilton Oat appears to be more affected than Sandy and 
Victoria, or Polish Oat worse than either.” 
Specimens of Eelworm attack were also sent me from various 
English localities. 
On June 11th Sir Francis Geary, Bart., of Oxon Hoath, Tunbridge, 
forwarded Oat-plants affected by “ Tulip-root.” 
The following note, sent me by Mr. James Rawlence, of Bulbridge, 
Wilton, Salisbury, on July 12tli, with specimens of bad attack of
