content: Original caption: 618-G71-D "Wrong motions of an inexperienced worker folding cloth in a textile factory. This picture shows intermittent electric lights with the filament and the current so proportioned that the light brightens quickly and dies out slowly. This gives us a photograph of time in that the number of flashes per second is known. Moreover, the point on the spot shows the direction of the motion. It is very easy to check up the efficiency of the motions in this way.

Note that #618-G71-B shows an inexperienced girl: also #618-G71-C and #618-G71-D. While #618-G69-2 and #618-G69-3 show girls with much greater experience. And it is here that our method is important; in that, in the scientific selection of the worker, we do not separate the workers into the two classes of those who are efficient and those who are not efficient, until we have determined the difference in their motions and have given the worker time to correct this difference. The difference show in these photographs is that the inexperienced worker does not even make curves; the lines are jerky, both in deviating from a straigth or evenly curved line, or are jerky as to time. This latter can be told by the difference in spacing between the spots in any one line." (Purdue captions).

618-G70-1 Shows the front view of woman folding pieces of cloth; or, in other words, ten cycles of the same operation as shown as one in 618-69-1 and as shown from her right side in 618-G70-3, and from her left side in 618-G70-2. It will be seen in each one of these pictures that there are certain deviations from the standard paths, and this is due to the fact that the pieces of cloth were not handed to the operator under standard conditions. With the exception of these special deviations the path of Ahabit is very clearly shown.

618-G70-2 This picture shows ten cycles of folding ten handkerchiefs. The single motion of execution shown on top of this cyclegraph is for turning handkerchiefs around that were not brought to the worker in the standard relative position with the rest of the pile.

Right view of operation of 618-G70-1.618-G70-3 618-G68-2 shows left side view of motions of folding handkerchiefs and 618-70-3 shows right hand view of same motions repeated ten times, or the folding of ten similar handkerchiefs. The marks of habit are strongly shown in this photograph, and the exception motions are due to the necessity of turning over handkerchiefs that were supplied with the initial in the wrong corner. The camera was moved slightly sideways during the process of the folding, showing the chronocyclegraph stretched in order to more easily count the different lines. This is shown by the double lines on the boxes in the right hand side of the picture. 

618-G70-4 See 618-G69-4618-G71-C Shows an untrained worker folding material. This picture shows a cyclegraph where there is an ideal illustration of awkwardness, clumsiness, mental hesitation and indecision at each turning point of the cycle.This picture shows a cyclegraph where there is an ideal illustration of awkwardness, clumsiness, mental hesitation and indecision at each turning point of the cycle.  Shows an operator making more than 150 motions in folding one of these pieces of cloth. The operator was an expert in this type of folding."Note that #618-G71-B shows an inexperienced girl: also #618-G71-C and #618-G71-D.
