The designer of this bulletin first had in mind something of the sort for the use of his students, not only the undergraduates, but others living on farms, or teaching in Michigan and elsewhere. Whoever grows seeds to sell, or buys seeds to sow, should be benefited by consulting the illustrations which are unsurpassed for accuracy by anything in this country. They were all made by Mr. F. H. Hillman. A hand lens costing from twenty cents to a dollar is almost indispensable in examining our seeds. The brief descriptions are necessarily made by using definite scientific terms, which are explained in a glossary at the close of the work. A few weeds are not illustrated, for the reason that the plants have ceased to produce seeds, such as the horse radish, and some of them are not conspicuously bad. Not far from half the illustrations are made from small seed-like fruits, likely to be mistaken for seeds, such as are produced by dandelions, burdocks, narrow-leaved dock, all grasses. Cuts of seeds of several clovers are inserted that students may learn to distinguished them from weeds too often mixed with them. No apology is offered for making use of the decimal scale instead of the cumbersome antiquated English scale, which fortunately is gradually growing out of use. In the back part of the bulletin are duplicate copies of the decimal scale that any one can cut out and use for measuring.
