MISCELLANY 229 
Dr. A. D. Hopkins, at present connected with the 
Bureau of Entomology of the Department of Agricul- 
ture, but formerly of the West Virginia Experiment 
Station, for many years grew timothy for seed. For 
this purpose the crop is ordinarily sown thinly, so that, 
during the first harvest year, the plants are sufficiently 
distinét to permit of the observation of individual 
plants. Many years’ close observation showed that 
the crop consists of a large number of constantly re- 
curring forms quite easily distinguished. A number 
of plants, each representing one of these forms, were 
taken up and separated into as many parts as the 
nature of the case permitted; in this way each plant 
became the parent, by division, of a large number of 
plants, all set side by side in a plat. When seed was 
harvested from these plats it was found that the 
plants produced from these seeds reproduced faithfully 
the characters of the original selection. Each original 
selection, therefore, became the parent of a variety. 
Several of these varieties are now growing in the grass- 
garden of the Department of Agriculture, where they 
have been the object of careful observation. They 
differ markedly in character of growth, earliness, size, 
etc. Some of them are evidently far superior to the 
ordinary timothy as grown by farmers (which is a 
mixture of superior and inferior varieties), some for 
seed production, others as hay plants, and others as 
pasture plants. (Some of Dr. Hopkin’s varieties of 
timothy exhibited at the Paris Exposition are shown 
in Figs. 46 and 47.) 
In a manner exactly similar, Mr. A. B. Leckenby, 
Director of the Eastern Oregon Experiment Station,
