the two varieties are compared in this way there is even a greater 
difference between them than is indicated by the records of time of 
blooming and maturing. In the plots from which these records were 
obtained in 1922, on each day from about July 1 until nearly the end 
of the month, the number of ereen leaves in the plots of Huron 
timothy were as great as they had been in the plots of ordinary timothy 
at least 10 or 12 days earlier. 
The illustration on the cover of this leaflet shows a plant of Huron 
timothy in full bloom. 
Number and Length of Stems 
Studies have been made at North Ridgeville of the characteristics 
of the stems in plots of Huron and other selections — varieties of 
timothy. 
In any timothy meadow in late spring or early summer two distinct 
types of stems may be found, namely, those that have produced

heads, and also those comparatively short, leafy stems on which no 
seed heads have developed. If the stems of the latter type are left 
to grow until late summer or fall, their general characteristics remain 
unchanged, and no heads develop on them after the time in the season 
when timothy heads ordinarily appear. On stems with heads, all 
leaves become dry about the time the seed ripens; on the upper parts 
-of the shorter stems without heads, on the other hand, there are green 
leaves for several weeks or even months. 
In each of the different years in which observations were made, the 
number of stems in typical square-yard areas in plots of Huron 
timothy have been compared with the numbers of stems in corre- 
sponding areas of ordinary timothy growing in the same series of 
plots. In practically all of these comparisons the total number of 
stems in the plots in meadows of Huron timothy have been greater 
than in the plots of ordinary timothy. This tendency may also be 
observed in plants that have been transplanted to row plots, where
