- Editor's Notes
- Water chalks wre sent yo with shipment of thirty sent from here r on Nov 11 and also on shipment of eighteen sent from here on 12th with the latter shipment were also sent one hundred extra water chalks. Throw away all chalks sent with Lighthipe's apparatus-- After rurning these water chalks wet with a brush full of pure distilled water which can be procured of any manufacturing chemist. After wetting, you will find the instrument leower than a Bell telephone, put it away for twenty four hours, then try it, polish it slightly and you will find it belch out, then proceed it will continue as we believe almost indefinitely-- You will find them the loudest you have ever heard-- These chalks should they ever play out say in 3, 6, or 12 months will I am sure be resuscitated by another brushful of the water-- We shall ship you a lot of water chalks with every shipment of telephones so you may have plenty to turn-- Bergman's first hundred and our last shipment were old style bells our next lot and his second hundred will be relays and bells-- We have had an exchange up here with all your wires going for the last week with relays and bells and water chalks and with this exchange I learn the insprectors by going roun to an instrument and damaging it thus setting him to find it, they have got so expert now, that any bug I can makde does not take them above 3 minutes to find. We have tested the water chalks very severly by baking for long perods and drying in air but no test that we can make seems to hurt them. Any transmitter, any coil, any spring, any adjustment seems to be good now. It is the old story get the chalk conditions just right and anything will work-- No more nursing!!! Batch and I tested 37 in 1 hour and 20 minutes having to set all transmitters too what do you think of that?
