MICHIGAN WEEDS. 283 



Central Hill, Norwood, London, S. E., who made his first report in 

 1872, and continued in service certainly until 1905. His successor is 

 still acting in the same capacity. Members of the society ca*i avail 

 themselves of his advice by paying a small fee varying in amount accord- 

 ing to the service rendered. Although but few farmers avail themselves 

 of the advice of the consulting botanist, the purity and quality of grass 

 seeds and those of other forage plants, rapidly improved, until today 

 there is very little cause for complaint.
