3818 APPENDIX. 
I think that this latter portion may be considered as representing 
a good average crop, equal to forty-five thousand kilogrammes of 
beets to the hectare. It is on these figures that I institute my com- 
parisons. 
For this plot the plants had been raised in a bed, and the plantation 
was made during the early part of May. 
In another plot, which was sown broadcast on the 18th May, merely 
a few blades made their appearance. ‘They had greatly needed weed- 
ing during the early stages of their growth, and had been, in conse- 
quence, much retarded. The yield was on a basis of 38,000 kilo- 
grammes to the hectare. | 
A third plot, raised in a bed, and planted in the garden, was not 
weighed ; it was gathered from time to time, as wanted in the experi- 
ments for determining the periods of the development of the sugar ; 
but I do not fear to deceive myself, in rating its yield, according to 
the appearance of the plants, at about half that of the 5m32 lot before 
mentioned. 
I have obtained as a result from the stalks, without leaves, an 
amount of juice equal to fifty or sixty per cent. Of course, if the 
tops are closely trimmed, or if we experiment simply on the selected 
stalks, a much larger proportion will be obtained. With proper ma- 
chinery it should easily touch seventy per cent. In the trial of 
October 30th, (made with the village cider press,) on 215 kilogrammes 
of stalks, large and small, from which only the tops and last joints had 
been trimmed, 106 litres of juice were obtained, showing a density of 
1:052. I calculate at least fifteen litres as lost in dampening the sur- 
faces of the stone and press. 
I have none of the sugar from the sorgho; have simply made some 
trials with the saccharometer, decided usually by an evaporation and 
a comparison with alcohol. 
The following is the proportion of sugar in the sap of the plant 
gathered at Verrieres : 
iain Oct: 1853; ..- z - 10:04 for 100 of sap.
