I have when travelling, so often wished for some little indication of the scientific features of the country, beyond the meagre information of the guide book, that it occurs to me to suggest collaboration amongst mineralogists for mutual information.

With a view to this, could we not agree to take some localities and work out their details, spending our holidays in un-hackneyed districts, at quiet inns and in fresh air, each reporting his results succinctly in the Mineralogical Magazine, with a sketch map where wanted ?

As a little-worked-out place, I for my part nominate the Val d' Anniviers or Einfischthal, leading from the town of Sierre, in the valley of the Rhone, at nearly right angles to it, into the very heart of some of the suhlimest scenery of the Swiss Alps, and, as it will be seen, affording great facilities for meteorological, botanical, geological and mineralogical studies, economical quarters, warmhearted people, and excursions and scrambles of every grade of length and difficulty.
