FlC I out of the c-omb the operator is aware of it, by the in the weight as he holds the crank in his hand; but with the heavy, unwieldy machines the stopping and starting take more time than doing the work. The same objec- tions apply to making machines for emptying four combs at once. They re- quire to be made much larger, and are correspondingly heavy and ; After trying extractors with revolving cans we found them so unsatisfactory that they were also given up. Experiment also enabled us to decide the distance the combs should be from the spindles; and this is of great importance, because if the combs are too near, as in some extractors we have seen, all the honey is not extracted; and although it may be convenient to have a can as small as possible in diameter, yet there is a limit to the minimum size for securing efficiency. In experimenting many. hundred combs were extracted and care- fully weighed, the bees allowed tO' clean them, after which they were again weighed. The difference in the weights enabled us to determine the amount of loss in honey, and by this means we were enabled to arrive at the most suitable measurements. Before proceeding we must here remark that no zinc or galvanised iron should on any account be used for extractors, or for any utensils for the reception of honey. The acid in the honey acts upon the zinc, and the oxide of zinc quickly poisons the honey. The same applies to galvanised iron, as the galvanising, as it is called, is only a coating of zinc. Nothing but tin or tinned iron should be used, and all iron parts coming in con- tact with honey should be tinned. We have always strongly insisted upon this, and have several times given our reasons for it in the Bee Journal. The illustrations, will, we hope, assist in better understanding the construction of one of these extractors. As we have a standard frame we will give dimensions suitable for this frame,
