2 THE PHYSICAL PROPERTIES OF SOILS 



The character (T) following' the name of a piece 

 of apparatus means that it must be obtained from the 

 instructor. 



At the close of each experiment all apparatus must 

 be cleaned thoroughly and returned to its proper place 

 before credit is given for the work. Full notes on 

 each exercise must be made at the time the experi- 

 ment is performed. The final report must be made on 

 the blank pages in this book, and should contain (i) 

 a description of the experiment and apparatus used, 

 (2) the results in a neat tabulated form, so that their 

 story can be quickly read, and (3) a short discussion 

 along the lines indicated on the direction sheet. 



The references given at the close of the exercises 

 are to be read before the experiment is written up. 

 All books to which reference is made will be kept on 

 a table in the laboratory or adjoining room, where they 

 will be accessible to the students during laboratory 

 hours. 



Write your name and the hours during which you 

 are due in the laboratory on the card attached to your 

 desk. 



This book is not to be taken from the laboratory 

 except by special permission, but must be left in the 

 place designated by the instructor.
