Dear Sir,

I have collected photographs of snow crystals during the past 20 years, & now have a collection numbering over 1100 no two alike. It has been almost a life work with me, & conducted entirely at my own expense. In addition to the photos of the snow crystals, I have secured some 150 more photographs of frost & ice crystallization, of great beauty & interest. My collection of both frost & snow crystal photographs are each in their class—

far superior in both number & beauty & I might add interest, to that of any other collection in the world, & picture quite completely the crystalline forms of water. The great majority of these negatives are in my possession, & no copies of them, except on paper; (& some lantern slides, at various Institutions,) are preserved anywhere in fire proof buildings. I have felt strongly for some years, that some institution, & especially the Smithsonian Institution, should, possess indestructible permanent copies on glass, of at least the choice photographs of my collection. The danger from fire, & lightning, or accident here at my home is not to be ignored, & has caused me much anxiety. It seems to me that such a collection as mine should be placed beyond the possibility

of destruction by fire or accident. This is my excuse for troubling you in the matter, & I write to ask if there is not some fund available from the Smithsonian Institution, or elsewhere, that can be drawn upon to defray the expense of making copies of these on glass, to be stored, & kept for study, at the Smithsonian Institution. I have been to so much expense making my collection; far more than I could well afford; that I do not feel as though I could even do the photographic work, developing, exchanging etc, free gratis, but I would willingly do it at very low wages, indeed. The expense of making the negatives would depend upon whether the copy desired was to be a positive, (first copy), or a negative, (second copy), & in the case of the

positive, I think the expense would not exceed 15 cts each, & if the negatives but 25 cts each, or possibly 30 cts. If but 500 of my best examples were copied in this manner, it would be a great relief to me, I would cast but about $80.00 for the positives, & about $150.00 for the negatives, (if the latter were desired, instead of the former.) Should you, through your great influence, bring about the desire I have so long cherished, I shall be deeply grateful, & I should you wish to publish a monograph, or article regarding the snow or frost crystals, in the quarterly issue of the Smithsonian publications, I will gladly write, or furnish data for it. (I think you mentioned desiring such an article, in a letter to Prof. [Cleveland] Abbe.)
