` _ y keep their premises free from such pests. On both these accounts, _  
1 J therefore, it is important that attention be called to the dangerl ·i

  · ._   The difficulty of freeing seeds entirely from foreignseeds when · ; _
l t the latter are much like those of forage plants in size and weight is ·
V   f fully appreciated by us. Yet, the completeness with »which_lit is _
{ ili` F   done in some cases encourages the belief that it could, if made 0 ·
l   necessary, be done in all cases. A report on`the?lsamples of seeds
C   p studied, is now in the hands ofthe Director   the Station for ‘
__   ~ publication, but the importance of this matter of weed seed dis-
_   I - semlination demands that it be presented to farmers and seedsmen
_     { { more fully and in greater detail thanlcould appropriately be done
_1 _{ i { _ in a report of examinations required by the law., v ‘ _
- Vi ;j   l   As an outcome of our work, it is suggested that the law should i ‘
;_       be amended to require that no field seeds be sold in this State, ·
Q     . having more than 5 per cent. of weed seeds mixed with them. This, · ,
 [   I believe, will be a fair allowance for _the weed seeds gathered by
N`?     accident, or left in samples after reasonable precautions have been
    taken to free them from impurities of this sort. .
  _._   l The following accounts of the forage seeds dealt with in the
  ‘ j law now in force, of the seeds used as adulterants and of the l
    I weed seeds found by us in Kentucky samples, are presented —in the l
  f Q hope that they may serve to familiarize our people with the impur- _
    ities of forage plant seeds and thus help toward checking the sale ·
      of impure seeds ia the State. - ' »

  { KENTUCKY BLUEGRASS AND ITS ADULTERANT. p
    The seed of this plant is, when ready for the market, enclosed ’ {
    in chaify scales by which it may be recognized by one who has `
  l given it close attention. But the resemblance of the seeds to those '
  l of its near relative, the so—called Canada bluegrass, is so close that
    adulteration with the latter is very likely to escapedetection. ·
    Seeds of Kentucky bluegrass, when in a mass are of a deeper l
    brown color than Canada bluegrass, and average larger. Examples, ~ I
 Q p measure from 0.10 to 0.15 inch in length, are sharply keeled S
    A along the back, the sides with two evident longitudinal veins. The .
