fitted to do in the Army (Navy). I'm going to pass around some papers now. Don't turn the pages until I tell you to." 

 Have the papers distributed. 



When all the men are supplied, say: "In the Army (Navy) you often have to listen to commands and then carry 

 them out exactly. I am going to give you some commands to see how exactly you can carry them out. Listen closely. 

 Do what I tell you to do as carefully and quickly as you can. Some of the things will be very easy for you. Some 

 you may find hard. Ask no questions. Attend strictly to business. Don't watch any other man to see what he does. 



"Now, on the page before you, write your nanie after the word 'Name.' Write your first name first, then your 

 middle initial, if any, and your last name. Take time to write very plainly." 



After name has been written say: "Put your age in years after the word 'Age.' 



"In the next line write your company, battalion, regiment, and division. 



"In the next line write the name of the country in which you were born. If you were not born in the United 

 States tell next the number of years you have lived in this country. After 'Race,' write the word 'White.' (In ex- 

 amining negro troops substitute the word 'Negro.') 



"In the next line, after 'Occupation,' write your usual work, trade or business (such as carpenter, grocery clerk, 

 laborer, farmer, student). 



"Next put down how much you earned a week before you entered the Army (Navy). 



" After 'Schooling' draw a line under the highest grade or school you attended. For example, if the highest grade 

 you attended was the fifth grade, draw a line under grade 5; if you finished the second year in the high school or 

 preparatory school, draw a line under high school, year 2, etc. (Explain further if necessary.) 



"Look at your papers. Just below where you have been writing there are several sets of forms — squares, circles, 

 and so forth. First you will be told to do something with the squares at 1. afterwards with the circles at 2, and so on. 



"When I call 'attention,' stop instantly whatever you are doing and hold your pencil up, with your elbow on the 

 table — so. Don't put your pencil down to the paper until I say 'go.' (Examiner lowers his pencil.) Listen carefully 

 to what I say. Do just what you are told to do. Ask no questions. As soon as you are through, pencils up. Remem- 

 ber, wait for the word 'Go.' L " 



N. B. — Examiner: Give the following directions very distinctly and at moderate speed. After giving the com- 

 mand "Attention, 8 ' the examiner should always notice carefully whether all pencils are up and never proceed until 

 they are. This is especially important in the beginning. Be careful not to pause or to drop the voice in the course of 

 the compound direction — e. g., in 2, before the words "and also." Raise your pencil whenever you say "Attention." 

 Lower it promptly whenever you say "Go. " Be careful to use the directions for test 1 that fit the form of record blank 

 distributed.
