ISJos. 41, 42 and 43 grown by Mr. Gayford, Preston. 
In the preceding tables I have placed side by side the compo- 
sition of some of the best and some of the worst roots which 
were grown in 1868 in the neighbourhood of Lavenham. It 
will be seen that No. 33, weighing nearly 3 lbs., and being the 
heaviest of the 11 roots, yielded a high percentage of sugar, and 
No. 38, weighing lbs., a still higher percentage, namely 12 
per cent. 
Comparing No. 38 with No. 39, and taking no account of 
minute differences, it will be noticed that the larger of the 
2 white Silesian beets, both grown on the same farm, was rather 
the better of the two beets. 
On the other hand Mr. Biddell's red-skinned Silesian beet, 
weighing only 3 ounces more than the white (No. 38), contained 
about 4^ per cent, more water, and only just half the amount of 
sugar found in the white. 
The difference in the composition of the white and red 
skinned Silesian beets, grown by Mr. Hustler, East Hill, is very 
striking. The white beet (No. 33), though heavier than the 
red skinned (No. 34), in round numbers contained 5 per cent, 
less water and 4-| per cent, more sugar than the latter. 
Of the 11 roots, 1 had an orange coloured skin, 5 were red- 
skinned and purple-top roots, and 5 white and green-top beets. 
All the 5 red-skinned roots were inferior in quality in com- 
parison with the white beets grown on the same farms on which 
the red were grown. 
The 5 red Silesian beets were much more v/atery, and poorer
