L'acqua è necessaria per le api per sciogliere il miele, che talvolta granulati nelle cellule per digerire il polline e per preparare il cibo con cui si nutrono la larvse. Essi possono sollevare una certa quantità di covata senza acqua, ma non sempre sembra soffrire di più o di meno in conseguenza (663). In inverno, essi razza ma poco, e l'umidità che si condensa sulle pareti dell'alveare è generalmente sufficiente. Ancora Ave hanno notato che non appena le api vengono portati fuori della cantina (653), se la temperatura è sufficientemente caldo,

. Langstroth on the hive and honey-bee. Bees. WATER. 129 Water. 271. Water is necessary to bees to dissolve the honey, which sometimes granulates in the cells, to digest the pollen and to prepare the food with which they feed the larvse. They can raise a certain amount of brood without water, but they always seem to suffer more or less in consequence (663). In the Winter, they breed but little, and the moisture which condenses on the walls of the hive is generally sufficient. Yet Ave have noticed that as soon as bees are brought out of the cellar (653), if the temperature is sufficiently warm, a great many will be seen sucking water. This fact shows that Ber- lepsch was right when he advised bee-keepers to give water to bees during Winter, to avoid what he called disease of the thirst. Besides, every one may notice that bees take advantage of any warm Winter day to bring it to their hives; and, in early Spring, may be seen busily drmking around pumps, drains, ' and other moist places. Later in the season, they sip the dew from the grass and leaves. 273. Every careful bee-keeper will see that his l)ees are well supplied with water. If he has not some sunny spot, close at hand, where they can safely obtain it, he will fur- nish them with shallow wood- en troughs, or vessels filled with floats or straw, from which — sheltered from cold winds, and warmed by the genial rays of the sun—they can drink without risk of drowning. A barrel half filled with earth and then filled with water, in which some water- cress or other aquatic plants are kept, to preserve it from putrefaction, and to prevent the bees from drowning, will do very well.
