son County, Colorado," and not "garnet, Colorado." Unidentified min- 

 erals should be marked with full information as to mode of occurrence, 

 in order that they may be properly studied later. 



It is always wise to preserve a record of the materials in some form 

 of field notebook. 



PACKING FOR SHIPMENT. 



For the transportation of the material to a place where it can be 

 properly culled and packed a leather bag is convenient. This should 

 be made twelve inches wide, twelve inches deep, and four inches 

 through, of stout leather (fig. 8). It should have a flap over the top 

 and extending ftilly six inches down the opposite side, and have a strap 

 and buckle to fasten it in position. 



The carrying strap should be of strong leather, two inches wide, and 

 long enough to go over the shoulder. This should be provided with a 

 buckle so that its length may be adjusted to the wearer. 



This style of bag is of course not a necessity, and any sort of a 

 receptacle may be substituted for it, but some means for the conven- 

 ient transportation of specimens in the field must be provided. 



A supply of paper, preferably of newspaper, is also indispensable 

 for wrapping specimens. Never attempt to carry a specimen unwrap- 

 ped in the bag. The material collected must not be permitted to chafe 

 or rub.
