" Drilling ami sowing of turnips commenced on the 12th of June; 
the drills were deeply formed and slightly harrowed down, and bone- 
dust (no drill used) at the rate of 20 bushels per acre sown with the 
hand, previously watered to encourage fermentation. The sowing was 
continued on the 22nd. On the 21st I had a bushel of the finest dust 
sifted out, which was mixed with 29 lbs. of sulphuric acid, previously 
diluted with .5fi lbs. of water, and having stood for twenty-four hours, 
was further diluted with about IGOO lbs. of water, or IGO gallons, and 
applied with a watering-pan to the drills harrowed down as before men- 
tioned, and sown on the 22nd. Tiiis quantity was applied to fifteen 
drills, containing 1 rood 6 falls, Scots. In this case 6 lbs. moi'e sulphuric 
acid were used to the bushel of dust than on former applications, and 
with advantage, reducing the bones more effectually. On the same day, 
to eighteen drills, containing 1 rood 15 falls, I applied Ix cwt. guano, 
mi.xed up the day previous with 3 bushels of bone-dust and 5 of saw- 
dust, in all 10 bushels of mixture, intended for J an acre ; but being 
smaller than bone-dust, it went through the hand faster, and only went 
over 1 rood and 15 falls. On the same day, and immediately adjoining, 
bone-dust was sown, at tlic former rate of 20 bushels per acre. On the 
23rd I sowed thirty drills, containing 2 roods 11 falls, with 10 bushels 
of bone-dust, applying in the morning to the bones 38 lbs. of sulphuric 
acid diluted with 63 ll)s. of water; and on the same "day bone-dust was 
sown in the usual way." 
" The turnips sown with bones on the 12lli of June came to the hoe 
on the 12th of July. The fifteen drills sown on the 22nd with the 
solution of sulphuric acid and bones were equal in every respect, and 
came to the hoe at the same time, though ten days later in sowing. The 
eighteen drills sown with guano and bones were four days later than the 
sulphuric, but six days before the bone-dust. The thirty drills sown 
with 10 bushels of bone-dust and sulphuric acid gained six days in 
hoeing on those sown the same day with bone-dust alone. At this 
period the difference betwixt the applications and the bone-dust sown in 
the usual way was most marked, and could be observed at a considerable 
distance, showing decidedly the great advantage in seasons when the 
turnip-fly prevails. The turnips were all hoed as equal as jiossible, and 
treated in every way the same. On the morning of 12th of November, 
the day of inspection by the committee, part of two drills of each 
experiment, measuring 335 imperial links, or 73§ yards in length, was 
pulled, carefully topped and tailed, and carted home separately, and cor- 
rectly weighed — the result of which was as follows : —
