character of that tribe. The Porno, the Twana, and the Hopi, make 

 each half a dozen st3des of baskets. 



VII. Collections. — Those collections that have been made with a 

 view to permanence should be kept so that they will suffer least from 

 damage. The dust ma}^ be blown from the specimens with bellows. 

 Those containing remnants of vegetable matter, berries, -food, and so 

 forth, should be carefully scrubbed with soap and water, and rubbed 

 down with a very small portion of oil and dryer. Above all they 

 should be poisoned with a weak solution of corrosive sublimate or 

 arsenic dissolved in alcohol. A card 



catalogue giving the legend and history 

 of each piece would add much to the 

 value of the collection. 



VIII. Bibliography. — Every con- 

 tribution to the literature of the sub 

 ject should be sent to the Division of 

 Ethnology in the United States National 

 Museum for safe-keeping and ready 

 reference. 



PROCESSES OF MANUFACTURE.

COARSE CHECKERWORK.

The various processes of manufacture 



will now be explained more definitely, 



and also illustrated. 



A. GheckeTworh. — This occurs especiall}^ in the bottoms of many 



North Pacific coast examples, and also in the work of eastern Canadian 



tribes (fig. 1); in mat- 

 ting its use is well-nigh 

 universal. 



In this ware the warp 

 and the weft have the 

 same thickness and plia- 

 bility. It is impossible, 

 therefore, in looking at 

 the bottoms of the cedar- 

 bark baskets and the mat- 

 ting of British Colum- 

 bia (fig. 2), or Eastern 

 Canada, to tell which is 

 warp and which is weft. 

 In very many examples 

 the warp and weft of 

 a checker bottom are 

 turned up at right angles 



to form the warp of the sides, which may be wicker or twined work. 



A great deal of bark matting is made in this same checker work,
