Note 1 — Chapter VIII

One object of this was to prevent what was called "robbing." While the pressure of the wind might be ample and steady enough with only a few stops drawn, it was found that when all the stops were drawn the large pipes "robbed" their smaller neighbors of their due supply of wind, causing them to sound flat. By giving each pipe a pallet or valve to itself, the waste of wind in the large grooves was prevented. Another object was to get rid of the long wooden slides, which in dry weather were apt to shrink and cause leakage, and in damp weather to swell and stick.
