| E.{Mr Elliott - Chief Engineer} from Hs.{Lord Ernest Hives - Chair} X3579 Hs{Lord Ernest Hives - Chair}7/LG12.9.21. AUTO-VAC. We have despatched to you to-day the mechanism for an Auto-Vac Tank. This is the latest one we have received from the makers. We certainly think, to make a success of the Auto-Vac system we should make a tank to hold at least one gallon.
