with Arabic numerals beginning with I, e. g., Fig. i, Fig. 2, 

 etc.; this number should be placed below the drawing. 

 Every part of each figure should be named by drawing a 

 fine, straight line from the part to the exterior nearest the 

 point indicated and placing at its end an appropriate abbre- 

 viation in an upright position. The guiding lines are best 

 made with the aid of a ruler; they may radiate out in all 

 directions from the figure or be arranged in a parallel man- 

 ner to suit the situation. All labeling should be done with a 

 lead pencil ; ink should not appear on the plate. 



6. Reference sheets of note paper, written in ink, should 

 face each plate, bearing the words "Explanation of Plate' 

 followed by the plate number in Roman numerals, on the 

 line at the top of the page. On the reference sheet each 

 figure should have a descriptive or explanatory title, full but 

 concisely stated, giving the object of the drawing, condition 

 of the material, point of view, enlargement, etc. At the 

 close of the list of titles give an alphabetical list of the abbre- 

 viations used, with their meaning. 



7. If any of the above points are not clear to you, consult 

 a sample notebook which will be provided. 



D. Corrections. i. At intervals throughout the term's 

 work you will be directed to place all drawings, reference 

 sheets and notes of whatever kind you wish criticized, in 

 one of the ' Hand-in Envelopes," in the proper order, the 

 first page facing the back of the envelope, and submit them 

 to the instructor for criticism. 



2. Criticisms of notes are not to be erased. Criticisms of 

 drawings made on the drawing paper may be erased. Criti- 

 cisms may take the form of a reference to a section and para- 

 graph of these directions.
