" The turnips were all of the same description, green-topped yellow. 
The soil was crpial. No farm-yard manure was applied to any part of 
the field.

" The turnips raised with the solution of sulphuric acid and bone- 
dust kept in advance, and came earlier to maturity, as also those with 
the guano. The early season was against them in this respect, as they 
were checked in growth much sooner than in an ordinary season. Had 
this not been the case, they would have gained more advantage in point 
of weight over the others than they have done. 
" To a different part of the same field, but a few days later in 
sowing, I sowed green-topped white turnips ; to a part of these I ap- 
plied 10 bushels of bone-dust per acre, dibbled in. These came up a 
very unequal braird, and were afterwards thin on the ground. To 8^ 
drills I applied i cwt. of guano, mixed with H bushel of wood- 
ashes and 2h bushels of saw-dust, in all, of mixture 5 bushels, intended 
for ^ an acre, but only went over 1 rood 23 falls. The turnips after 
this were a fair crop, and superior to that Avith the bones dibbled. The 
rate per acre of guano was 213 lbs., value 38^., exclusive of wood-ashes 
and saw-dust, and value of bone-dust 32?. 6d. per acre. No comparison 
was made as to weight. 
" To part of another field of poor thin soil, half manure was applied, 
and watered in the drills with a solution of bone-dust and acid, prepared 
as before, at the rate of 2 bushels of dust and 46 lbs. of sulphuric acid 
per acre, diluted with 112 lbs. of water, and afterwards reduced to the 
proper quantity. The turnips were sown on the 2nd of June, white globe 
and green top, in two alternate drills, intended for early eating oflr', one 
half to be pulled. The crop, considering the soil, was good ; but the dry 
early season was much against it. The other part of this field was 
sown on the 28th of June in the same way, and the same description of 
turnips. These came most rapidly on for the hoe, and were a good crop 
for the quality of the ground. For poor thin land I would decidedly 
consider this mode of application the most advantageous. There were 
only three drills left without the solution being applied to, and these were 
very inferior."
