Collection and Identification. 



Not only every seedsman, but every farmer, and every teacher 

 in a rural school, should have a collection of weed seeds for reference 

 and comparison, in order that he may be able to detect and identify 

 such seeds when they are in grass seed, clover seed, rape seed, or any 

 other kind of seed which is sold or offered for sale. A good collection 

 can be easily made in the summer months. All that is necessary is a 

 number of small bottles and a little attention at the right time. The 

 so-called homeopathic vials of one drachm capacity are suitable for 

 the purpose, but they should be carefully and plainly labelled. If 

 they are not so labelled, the collection will be valueless.
