BENTON & STONES FILTER. By means of an intensive laboratory test in Benzol and water, we succeeded in making the duralumin filter plates corrode. Whilst we think that this it is most improbable that this would ever happen in service, since there is a trap for water beneath the plates in the filter tumbler, we think that it would be wisest for Messrs.Benton & Stone to supply the first batch of filters with brass packs. We shall have done sufficient road testing in a month or so to say definitely whether we have anything to fear in the duralumin filter.
