Waphic paper I use. This is my own in- Nentioh, and for the present at least, pust remain a secret. It is here that 1 ss asne met with some of the sreatest dlf- ~Wuas iu ms work <>fhe Bdver .et,fireI tor the emulsion should be a tough stock paper such as fs used by manufacturers oi tho leading photographic papers. This kind or paper ia necessary ina smuch as uhe process of developing and fixing is q ions one. and the paper heinz wet and dried by turns for over one hour. The paper is printed when damp. and the amount of changes it has to undcrges Is dasa astrous to any but the toughest kind Of paper. The stock paper that rcfcr to is made only in Germapy and all that Is ssnt to this country is bought and com trolied by the photographic trust so shat it IS possible to obtain the stock paper until Il has been treated with the cTlul. sion of the concern which prepares the paper for market have been I,Ii.-i to buy this prepared paper. remove the emulsion and then apply my own emui- sion in order to get ahvthins arproa ming ss sstisfactorN results. This is both cxpe.- sive and not always as conducive to the wst work es l should wish, for the pa ncr Frequently bee omes roughened by so much manipulation. It ;s almost imp, ssible to secure paper that has not been treated With acids. and if these are present it spells the work of my preparation. The emulsion that l use has = he mixed up nesh Tor 1t has no keeeiaG properties. go

 Method of Printing.
 After negative is ready for printing aooht two hours work is required hcfcre finished picture Is ready. The printing Is done by dull light and it requires a great deal of experience to tell how long 2 tune is required for the best results ordinary printing frames are used and when developed; the prints have to be little variation ',,- the smallest detail Inskes a great difference with the per- eftten Of the finished picture.
 The cost of this work is not SO much as many people will at first ina zine con sidering the amount of time required in making the prints. The finished pictures WI! cost about four or five times as much as ordinary prints, but Of course are not t9 be compared from an artistic point of view. At present the method is onjv serviceable. as I said in the first part of the interview, where long exposure can he given. It will however be invaluable to those who have collections of birds minerals or other inanimate things that they wish photographed in original colors For instance | can photograph a paint ing and bring out the natural beauties of the original so that 1t will be impossible 10 detect the slightest variation. Tn this U VIII slfpaSs Water-coior drawings. for there 1t Is impossible to secure perfect reproduction of the original One of my first undertakings in this line will be the phofograpf1ng of the famous Hyatt col lection of Sandwich Island sea shells The collection was given to Harvard hy the late Alpheus Hyatt. Assistant Professor or Archaeology of Harvard University For many years before his death Profes- Sor Hyatt was exceedingly anxious to have a eolored reproduction of the shells Tor Illustrating purposes. The collection was such valuable one. costing many Thousands fh of dollars. that Professor hands Of the lithoeraphers. and it was only possible to secure any colored pio- lures or the shells by transportins the collection to the studio of some such cx- pert. The attachments used in this work ana me cameras are very cumbersome 90 that it was not eXpcdient tn undertake the shells at the museum where they were on exhibition.
 The only other method would have neen to have a water-color artist repro dnce the colOrings and then make a three coIor half-tone from that. This would nave been very expensive and not en- ireiN satisfactory for the shells arc beautifully sha ded. from the most deii- rare pink to the brightest blue. many of the colors shading into each etber in sach way as to give an iri1cscent effect To obtain that effect by any colored pheto- sraphic method known. or even by water color, would he out of the ouestion.

The method will | also he largely used by persons owning faluable oil paintings. for the finished l photograph will he as beautiful in color Is the original picture
