She got from me that afternoon the history of all the Polar expeditions of late years, how far they reached, by what aids, and why they failed.
Thus far we have referred to two systems, one the neutral or differential duplex, and the other the combination of the neutral and polar relays, making a diplex system.
You know and I know and we all know that there are a lot of things up there at the polar mines that would look like hell to anybody who didn't understand local conditions...."
In this manner I have kept dogs from the polar regions, in comparative comfort, whilst many native-born and neglected have been scalded into fits, paralysis, rabies, or hydrophobia.

This difficulty was solved by dividing the battery at each station into two unequal parts, the smaller battery being always in circuit with the pole-changer ready to have its polarity reversed on the main line to operate the distant polar relay, but the spring retracting the armature of the neutral relay is made so stiff as to resist these weak currents.
