return with his boat loaded with clams, the meat of which was given to the country-people in return of opening the shells, as they were ruined by boiling. The blue 'heart' of the clam, as it was called, was cut out, and made up into the beads used of the ground-work of belts. My informant said, further, that he had often paid out thousands of dollars per week, buying the beads of the white country-people, who manufactured them in their several homes. The ole of the bead was made with an 'arm drill,' and the beads were polished or rounded on grindstones. He xnys the white beads cannot Iw made from clam, but from conch shells, wbleb they hnre alnays im- ported from the Went Indies. The yonnji clams can- DOthe used, and tbeold have so decreased in number that this branch of the industry has been (jretitly re-

Although they had been familiar with f iidians. ihey bad never known of their making the beads. They had always depended upon Ihe trappers for their market, and re- lated incidents connected with their dealings with ' tar coinpiniea,' etc. The conch-shell la u&ed also in the manufaclure of the pipe beads, rosettes, etc. The holes in the pieces composing the rosettes are drilled, some of thetn, by the country-women in the vicinity.

'Waa It Imapnatioii ?
The note on artifleial auroras, in Seienre for Nov. 14, reminds me ot an asiwrienea which occurreii to ' myself and party on a mountain summit two or three years ago. There was an unusually brilliant aurora, and It was remarked by several that the streamers seemed in b^ very near tis ; and prexeul ly. as we stood In Ihe open air with heads uncovered, we began to feel the sensations proiluceil by proiimlly to n body charged with electricity. The fact thatsucli a Htnsa- tlon Had actually been produced by the aururn. was doubtrd by some sclent iHc men to wbomlmentloiieil it ; and It was attributed to imagliiatlon, which, I feur, la guilty of ttincli. and often ttccused of luore. My object now U uhielly to inquire whether others have had a stmllar experient^. 1(. during the exhibition of anauronk. such an artificial pillar of light can be formed. 1 see no reaion tor doubting the evidence of my own sense-; which, by the way, waa so deflnlle, and BO dittlnclly perceived, thai I couhl not dimbl it if 1 desired to du so.

We have sin-ccssfttlly passed wliot ia some- times calleil ' the dangerous second year.' A more intimate afqiiniiitnnce with our staff of contributors, aud a more accurate knowledge of the reciiiiivmeiits of ottr readers, have enabled tis from lime to lime to modify our original plans, and to .idii|jt llii'in more closely to the actual seieotifii; coiidilionor the country.

On tlic other hand, the teachers atid leaders of science would generally lie glad lo have this Joiiniat become more scientiRc. and leas rtojiidar, by printing longer paiiers than we commonly offer, more abstracts of important memoirs, more elaborate discussions of controverted ijoints. Between these two opposing tendencies, it is no easy task to keep a steady course. A brief recapitulation of our principles may enable our readers to understand our position.
