.after plouj^lnnpf we <jave one turn of the Norwcfjian harrow, 
then re-sowed the mustard as before. The whole field was 
finished on the 12th of July. 
The third crop was just breakinsj- into bloom on the 24th of 
Auf^ust, and the lenu^th above 5 feet; this was ])loughed-in 
8 inches deep, witli lour horses at lenjjth, followed by a two- 
wheel j)resser, followins: only one ploujjh, thereby giving; each 
furrow a double go. After one turn of the Norwegian harrow, 
the land was left to settle down for the future wheat crop. As 
for the couch grass, except a few blades in the first crop of 
mustard, we saw no more of it, except the rotten roots, as we 
were ploughing the last crop in. After one turn of the Nor- 
wegian harrow in the first week in October, the land was drilled 
Avith two bushels of red wheat per acre, a light harrow following, 
then twice rolled with Crosskill's heaviest crusher: it was 
crushed again in March. The produce at harvest was all that 
any man could desire, and perfectly clean. After one 8 inch 
winter ploughing, and a shallow scarifying in the following 
March, it was drilled with white oats and clover seeds ; the 
crop of oats was magnificent, and in some parts injured the 
seeds. Thenceforth this field, which had borne a very bad 
character, behaved as well as the best. During the succeeding 
seven years of my occupation of this farm, if I had to deal with 
any piece of very foul strong land, I cleaned it in this way ; but 
if it was moderately clean, I consumed the mustard with store 
sheep and lambs. Mustard crops grown after those eaten off 
will not be so heavy, but with a very little corn or cake they will 
keep from 16 to 24 sheep per acre, half ewes and half lambs, 
from the middle of May to the end of August, or even later. 
The ewes (or stores) should follow the lambs in a separate pen ; 
a fresh piece should be given every day, and the piece fed 
off should be ploughed and sown the same day, because in dry 
seasons whenever the land is naked the moisture is soon dried 
up ; thus there will be a regular succession, and also the almost 
certainty of a plant. 
The application of 1 cwt. of nitrate of soda to the first crop 
will almost double it, and, of course, much increase the two 
following crops, as well as their power to smother the twitch or 
other weeds. I know several persons who have made attempts at 
this system, but through dilatoriness in ploughing and re-sowing 
have failed to obtain a regular plant. I believe the Norwegian 
harrow to be indispensable to success, because it thoroughly 
pulverises the soil at once, so that lengthened exposure of the 
different surfaces k avoided, and much moisture saved that would 
be lost by repeated harrowing and rolling. If in a wet season 
rain falls and delays the sowing after an}' part is ploughed, this
