At the time these experiments were carried on it was imprac-ticable to make tests of the sucrose content of the beets to ascertainthe effect of the evaporation that took place, as indicated in the pre-ceding tables. After the writers return to Washington, D. C, some beets weretaken from the silo, carefully packed, and expressed to Washingtonfor laboratory tests. These beets were quite fresh and crisp whenreceived. Eight of these beets were sent to the sugar laboratory of theBureau of Chemistry on January 15, 1913. From each of them adiagonal core was rasped out for analysis. (Fig. 4.) Each end of. Fig. 4.—Sugar beets, showing the method of rasping out a core from individual beets to make sucrose determinations. the hole thus made in the beets was immediately plugged with arubber stopper, the beets being weighed before and after the corehad been taken out. The beets were then returned to the writer, who exposed themto a brisk current of air in a well-lighted room at a temperatureranging from 73° to 77° F. for 4 J hours, in which time the averageloss of weight of the eight beets was per cent. The beets wereagain turned over to the sugar laboratory, where a similar core wastaken from each beet for test. This was done shortly before noon ofthe following day. Meantime the beets had been kept in a coolchamber. As will be seen by Table VII, the beets lost as much whilein the sugar laboratory before being tested as during the exposure tothe current of air.
