TAKING OF NOTES AND SAMPLES. 
Form, of notebook used. — As every effort has been made to assist the 
driller in keeping notes and saving samples, special notebooks as well 
as sample bags were devised. 
On the front cover of the notebooks now in use" is the title, and on 
the back cover are printed a postal frank and the address of the Sur- 
vey, so that the book may be returned by mail without wrapping. 
Experience has shown that the books become much less soiled than 
was anticipated, little trouble being encountered in this line. 
The inside of the front cover contains the following simple direc- 
tions, prepared by Mr. Veateh: 
Suggestions to drillers. 
1. Samples should be taken from each bed passed through, and never more than 
20 feet apart, even in the same bed. 
2. Samples from wells in sands and clays should not be washed, as washed samples 
of sandy clay show only clean sand and give a wrong idea of the character of the bed. 
3. All oyster, clam, or other fossil shells should be placed in the bags with the dirt 
or sand in which they are found and marked with the depth from which obtained. 
4. Samples should be dry before being mailed. 
5. A blank label will be found in each bag. After it is filled out it should be folded 
once to protect the writing. 
6. Bags should be tied securely and mailed. They require no postage. 
7. In the first two or three samples sent in, the "Location" should be tilled out 
with care; in the succeeding samples so much care need not be taken with location, 
but the rest of the card should be complete. 
8. Note depth and thickness of all water-bearing layers. 
9. Note under "Remarks" the quality of the water from each layer, as hard, soft, 
salty, alkaline, or sulphur bearing. 
10. Note height to which water from each layer rises in well, and give flow in 
gallons per minute. 
11. Make frequent use of the "Remarks" column to explain your notes. 
12. If you leave the rig, send in your notebook with the name of your successor 
and a new book will be sent to him. 
13. If you do not understand what is wanted, or desire information on any point, 
write to this office, using one of the envelopes sent with the first shipment of bags. 
They require no postage. 
14. It sometimes happens that unauthorized persons represent themselves as mem- 
bers of the Survey. If you desire to know whether a man is connected with the 
Survey, ask for his identification card, which is signed by the Secretary <»! the Inte- 
rior and the Director of the Geological Survey. 
a A new edition to be used after January 1 varies in a number of unessential particulars from the 
form here described.
