yard. ‘The total cost of washing, chopping, putting into silo, and weighing 50 
tons of potatoes was £3, or about id. per cwt. The silo made on 20th 
November last was opened on 22nd January (sixty-two days later), The 
height of the silo at the time of erection was 54 feet, and on 22nd January it 
had sunk to a little over 8 feet. ‘The temperature of the mass was 39 degrees 
Fahr. at the commencement of the experiment, 42 degrees on 1st December, 
and 50 degrees on 22nd January. On taking out the potato ulp, ib was 
found to have retained its whiteness, but the parts exposed to the air after- 
wards blackened slightly. Cattle ate this potato pulp greedily, either alone or 
mixed with undecorticated Egyptian cotton-cake. The experiments are to be 
continued. ge 
M. Vogué read a third note on experiments made by M. de Monicault, 
who placed beetroot and potatoes in a silo of fodder maize. On opening the 
silo, neither beetroot nor potatoes had changed their appearance, although the 
tubers could be easily divided, as if they had been boiled in water. Analysis 
showed 4°5 per cent. of sugar in the beetroot. Distillation gave no trace of 
alcohol. As beetroot contains on an average 12 per cent. of crystallisable 
sugar, it would appear that two-thirds of the sugar had been lost in the 
ensilage. No soluble starch, dextrine, glucose, or alcohol were found in the 
potatoes; and ensilage appeared to have caused the desiccation of the tuber 
without baving cooked it,
