There are available several devices which may be 

 found convenient and time-saving where many bottles 

 are used daily. Among these devices may be men- 

 tioned a bottle-rinser (Fig. 23), a drain-rack (Fig. 

 24), and a bottle-washer (Figs. 2$a, b, and c), des- 

 cribed by Farrington (Bulletin 129, Wis. Agr. Exp. 

 Station, pp. 22-24).
