Pass it in this mannerthrough the water several times so that there will be nobubbles remaining on the surface of the fllm. When it isthoroughly wet the developmenf, may be commenced. HoId-ing the film in the same manner, pass the film through thedeveloping solution as described for wetting it, keeping itconstantly in motion. In about one minutc dark spots rvillbegin to appear. These are termed high lights, and very soonafter their appearance an image of the object will be discern-ible. Complete development in the strip by passing the filmthrough the developing solution until all the detail has beenbrought out in the thinest negatives.It will be noted that the negatives are of different density.This, horvever, is not an objection as this can be overcorn: i.nprinting. The difference in density does not affect the differ-ence in contrast. Kecp the strip r,r.hich is being dcvc)oped inconstant motion, allorving the developer to act from fire toeight minutes, depending upon the rapidity rvith rvhich thenegative gathers density. The progress of dcvclopment maybe watched by holding the strip up to the larnp from timeto time. It rs advisable, horvever, to make the examinationas short as nossible.Note: Io avoid transparent spots after having passed thefilm through the deveiopcr the first time face dor,vn, rcverse itand pass it through face up, holding the film dolvn in the lrayand dlarving it lightly through the developer under the hand.This ll,ill brcak ail the air bubbles. Tlansparent spots arecauscd by air bubbles adhering to the film rluring doelopment.After the development has been completecl, pass the filma ferv times through the clear rvater, thcn transferring it tothe tray containing the flxing bath. When al1 of the creamysurface hns disappeared from the unsensitizctl surface of lhefilm fixation is practically complete. It is, horrever, advisableto continue to pass the film through the solution trvo orthree minutes after the disappearancc of the creamy color.After the films are thoroughly fixed they should be washedin colrl mnning r.ater florn forty to sixty minutes. If run-ning water is not convenient, tcn changes of lresh water should- tz- 
						

							be used, keeping the fllms constantly in motion all the Ihile.The thorough lvashing of the films is very important in orderto remove all traces of the Hypo or else stains lvill appearafter drying and the negatives rvill be ruined,After washing, the films should be hung up to dry in sucha manner that it does not touch the surrounding objects. Theplace selected for drying should be free from dust. If a mildcurrent of air is present the process of drying rvill be greatlyquickenecl.The temperature of the developing solution should be asnear as possible to 65 degrees Fahrenheit. The fixing bathand water used for rvashing should be kept cold, ice beingemployed in extremely hot l-eather.
Cutting the Film for Separate Development-Figure 9
The use of f,he Ingento Developing Roller rvill greatly facil-itate the developing process. This device consists of a heavyglass roller lvhich revolves on trvo brass pins mounted inextra heavy nickel plated brass frame. Its otn rveight issufficient to resist thc oull of the film when it is being drarvnthrough the solution. ^When this roller is used only half thesolution ordinarily required need be made up, as the rollerover which the film is drawn is within 3/16 of an inch from-13- 
						

							the bottom of the tray, thus keeping the film entirely sub-nierged in less than one-half inch of solution. It is for usein trays 4x5 or larger and rvill accommodate any film 4lax61/2or smaller and can be obtained from all photo supply dealers.
Separate Development of Each ExposureIhe above directions apply to the developmerrt of the filmin the strip. It is sornetirnes advisable to develop each sectionseparately, especially lshere there has been a great variationin the exposures given. In this case the following directions !apply: EIn unrolling the film preparatory to developing in this _!manner, care must be taken that the end should not be allowed _c)to roll up over the paper. Ihe exposures shoulcl be cut apart !prvith the black paper on top so that the divisions betrveen 6each film can be readily recognized by the numbers which aappear on the edge of the black paper. Do not let the fingers =touch the face of the film. The face is the dull side. The ipropcr maurer of holiling the fllm is illustrated by flgure 9. IAfter the film has been cut into sections as indicated above. l]place the scctions in the tray containing the cleer rvatcr, to ei.,morr air bubbles, covering the tray li)ith a piccc of brown epaperorcardboardtoexcludethelightofthelamp.Take>one of the scctions from the water and immerse it face down Ein the tray containing the dcveloper; rock the tray gent)y to Iprcvent strealis and air bubblcs. In about one minute the €film will begin to darken, representing the high lights of the Cpicture, and in about two minutes the image vill be discern- Vible. The common way of determining rvhen the fiim has Ebeen fully developed is to look on the back to ascertain whether Fthe obiects in the picture have begun to show through. Whendeveloping films singly, from five to six minutes is usuallyrequired, the time varying according to the temperature ofthe solution.
When development is complete transfer the film to thetray containing clear rvater ancl rinse it trvo or three trmes,after rvhich it should be placeil in the tray containing thefixing bath. At this juncture the second section of the filmshoulal be put through the same process, care having been_ t4_ 
						

							taken that none of the Hypo has adhereil to the fingers, thusallowing rt to come rn contact with the undeveloped sectionof the tilm or with the developer.Three or more negatrr-es may be developed at one timeby placing the films in the dcveloper face dorvn and alter-nating each section so as to prer-ent air bubbles; however, r,verecommend that the beginner devclop only one section at atime until the neccssary experience has been gained. As eachsuccessive section is developed and lixed it shoulcl be placedin the rvashing rvater. After the films have been thoroughlyrvashed they should be pinned up separateiy to dry, care beingtaken that their surface is not allosed to come in contactrvith the surrounding objects.

Making PrintsThere are in general use, three classes of paper used formaking pictures; namely, blue print or ferro-prussiate paper,printing-out paper such as Solio, Disco, etc., and developingor gaslight paper, such as Rexo, Velox, Argo, etc. The firsttwo classes are for daylight printing only, .while the lastc.lass may be printecl either in subduetl daylight or by arti-ficial Jight.
Printing-Out Papers
Open the printing frame and place the negative face downupon the glass, then place upon this a sheet of blue printpaper. Replace the back of the printing frame and secure itwith the springs. It rvill be noted that the back of the print-ing frame is hinged so that a part of the print may be uncov-_ l5_ 
						

							eled for inspection during printing, without disturbing itsregister with the negative. The loading of the paper into theframe should be done in a subdued light, that is, in an ordi-nary room, but as far as possible from the window. Theunuged paper should be returned to its package for protectionfrom the light.
The loadecl printing frame should be placed glass side upin the strongest possible light, direct sunlight being preferred.It is allowed to remain until the image from the negative hasbeen sufficiently impressed on the sensitive paper. This canonly be determined by an occasional examination of the paper.Print until the shadolvs become a gray bronze color, or untilthe high lights are slightly tinged with blue. When this stagehas been reached remove the print from the printing frame,wash thoroughly in running water for 15 rninutes or in sev-eral changes of cold water, allorving the print to remain ineach bath a ferv minutes. After having thoroughly washedthe print as above inclicatcd, it should be hung up for drying.The Ingento Blue Print Paper is especially recommended asit is prepared especially for photographic purposes.When using a printing-out paper such as Disco, Solio, etc.,the frame should be loacled as directed above for blue printpaper. The printing should be allorved to continue until thetone of the print is somewhat darker than is desirable in thcfinished picture. Ingento Toning and Fixing Solution is highlyrecommenried for toning this class of p:rper. I{ix the toningsolution as dirccted on the package and pour it into a tray.The prints shoulil be immersed in this solution face dorvn soas to insure the even action of the solution over the rvholesurface of the print. After a moment or so, the print maybe reversed so that the toning can be watched. Repeat thisprocess from time to time during toning. Thc prints willbegin to change color immediately qpon immersion in thetoning bath. At first they are of a reddish brown, changinggradually to reddish yellolv, then to broln and then to purple.Toning should be stopped when the desired shatle has beenobtained. At this point the prints should be transferred toa salt solution made by dissohing one tablespoonful of com-mon table salt in 16 ounccs of vater. The prints should be_ 16_ 
						

							allowed to remain in this solution about 5 minutes, afterwhich they shouid be rvashed for one hour in running wateror in twelve changes of water. They are then ready foidrying,books and for this purpose \.\.e recommend Ingento BlatterSeveral prints can be toned simultaueouslr..Developing on Gaslight PapersDeveloping Papers, such as Rexo. \-elox, -{rgo, etc., arevery popular with arnateurs because of the simplicity in theiroperation, the excellent rcsults obtained and the added advan-tage of being able to print thern by artificial light. Thesepapers can be hanclled rvith safety eight or ten feet awayfrom an ordinarv gaslight. Thcy should not, however, beallou-cd to remain uncoveled in the direct rays of the iighteven at this distance for any considerable time. The paperis loadcti into an orclinary printing frame in the same man-ner as aboye desclibed for printing.out papers, taking carethat the emulsion side of the paper is against the dull sideof the film. The emulsion side of the paper can be deter-rnined by tendency of the 1,3pp1 to curil in that direction,or by biting a corner of the papcr, the emulsion side tendingto sticl< to the teeth. \Iith the back of the frame clamped inposition, it is exposed by holding it near a gas jet, lamp orincandcscent light. The length of the exposure depends uponthe distance at r.vhich the frame is held from the light, andthe density of the negative. Erposure can also be rnade insubdued daylight; hou,ever, artificial light is preferred, as itdocs not vary in intensity as is the case rrith daylight andit is therefore much easicr to judge the length of the exposurerecluircd,\Tith this class of paper no image is seen on the surface,until the print has bcen placed in the deleloper.lhe larger the negative, the greatcr the distance it shouldbe hcld from the light, the usual rule being that the properdistance is equal to the diagonal of the negative. The time ofexposlrre varies with the distance the printing frarne is heldflom thc light. If, horvo.er, daylight is used, it rvill befound advantageous to cover all the sindorvs with postoflicepaper, lvith the exception of an opening about one foot square.Ovcr this opcning ts.o or thtee sheets of tissue paper shouldbe pasted to diffuse the light, thcn use a piece of blacl< cloth_t7_
