Renaud had worked in the cave for two years, and asserted that they did not choose the night for carrying the ice down to the station, and did not even care to choose a cool day. He believed that, in the autumn of 1863, they loaded two chars a day for fifteen days, and each char took from 40 to 50 quintaux; the quintal containing 50 kilos, or 100 livres.

In Professor Pictet's time this glacière supplied the Hospital of Geneva, whose income depended in part on its privilege of revente of all ice sold in the town, with 25 quintaux every other day during the summer.

He told us that the amount of ice he sold averaged 4,000 quintaux métriques a week, for the three months of July, August, and September; but the last winter had been so severe, that the lake had provided ice for the artificial glacières of Annecy, and no one had as yet applied to him this year.

Since the quintal contains 50 kilos, it will be seen that this account does not agree with the statement of Renaud as to the amount of ice each char could take. No doubt, a char at S. Georges may mean one thing, and a char in the village of Chaux another; but the difference between 12 quintaux and 50 or 60 is too great to be thus explained, and probably Madame Briot made some mistake.
