 reference to its suitability to the crop to be grown and it is 

 also well to have a market in view before investing too heavily 

 in the enterprise. For one who has the leisure, collecting 

 some of the wild plants listed, might present some attractive 

 features. In that case he would do well to learn in advance, 

 the price he could expect and the chance of marketing his 

 product. 



The plants in the following list are those of the Pharma- 

 copeia. The scientific and common names are given, the 

 parts used indicated and the price, when possible, quoted. At 

 another time it is proposed to list our native medicinal plants 

 that are not official. For aid in preparing this article, I am 

 greatly indebted to Prof. O. A. Farwell of Detroit.
