- The gauging of spirit vessels and the gauging of contents of the same should be made in accordance with the instructions laid down in the Technical Excise Manual, but wet gauging should be done by withdrawal of the water as has been the method hitherto.The permanent store casks at the warehouses for reducing purposes should be of good standard shape viz., those which must nearly approach the spheroidal.In these cases the quantity measured into the cask will agree very closely with the quantities found from calculation by the bung rod and ullage slide rule.In the proper register it will only be necessary to state the number of each cask, its capacity as found by actual measurement and the discrepancy between this and the quantity shown by bung-rod calculations at one-fourth, one-half and three-fourths, of the capacity of the cash respectively.All casks must be properly fitted with taps of not less than three-quarter inch internal diameter. No part of the staves must be cut out, the bung hole being left intact. The number of the cask and its capacity must be marked on the wall above and immediately behind the place where it must always be kept when it contains spirit.The tap must be inserted in the usual place in the head of the cask close to the chimb.The bung must be stopper-shaped so as to combine the advantages of a handle and bung combined.Instructions for gauging by the dry method will be found in the Technical Excise Manual.
