second time with the hancl-hoe, and all weeds alon<? the top ot 
the ritii>e between the plants cut out, boys again iollowin<j:, 
to pull out any double plants that might have been left th;^ 
first time. From this date till the 20th of September, they were; 
regularly horse-hoed at intervals of about ten days with the 5- 
shared hoe, stirring the soil the last time to the depth of 8 inches. 
On the 11th of November a portion of the crop was t;iken 
U}), topped and cleaned, and the bulbs and tops weighed 
separately. 
The weight per acre was 35 tons 3 cwt. of bulbs, and 2 tons 
17 cwt. of tops, from 19,800 roots. 
No. 2, the next piece, was sown the ISth of May, on land pre- 
pared in exactly the same way as No. 1, and received the same 
quantity of farmyard manure, but no artificial. The plants on 
this piece came up partially, the land not being sufficiently moist, 
consequently they came up at different times. They were not 
ready for the hoe till the 24th of June, when they were set out ; 
the after cultivation was in every respect exactly the same as 
No. 1, only the number of plants per acre was considerably less, 
from being destroyed by insects. 
This piece was tested on the 15th of November, and gave 
28 tons 12 cwt. of bulbs, and 4 tons of tops, from 17,600 roots. 
No. 3 was sown May 24th, on land fallowed and prepared the 
same as for Nos. 1 and 2. This piece was grown in competi- 
tion for the 20Z. cup offered by Proctor and Ryland, of Birming- 
ham, for the best 5 acres of swedes grown with their manure 
only. The manure was sown broadcast, G cwt. per acre, and 
ridged in, the ridges being only 20 inches wide. They came 
up well, and were set out the first time the 24th and 25th of 
June. The narrowness of the ridges prevented the horse-hoe 
being used more than twice, and that at an early stage of their 
growth. This piece was early attacked by mildew, and suffered 
considerably, consequently the produce was greatly deteriorated 
in weight. 
The weight on November 15th was 22 tons 6 cwt. of bulbs, 
and 3 tons 2 cwt. of tops, from 20,400 roots. 
No. 4, a field of 22 acres, was sown from the 7th to the 14th 
of June on ridges 2t) inches wide. The manure used was 20 
(one-horse) loads of Avell-rotten farmyard manure and 2 cwt. 
of Proctor and Ryland's turnip manure per acre ; the artificial 
was sown broadcast after the farmyard manure was spread, and 
the whole covered in together. Those sown on the 7th, 8th, and 
lOth were up well on the 14th, showing throughout the whole 
length of the field. We commenced setting-out on the 24th, the 
soil being very fine, with plenty of moisture ; they grew remark- 
ably fast. This crop was deeply horse-hoed at short intervals till
