month. In Michigan, also, the same method is successfully employed 
by dairymen, the clover fields being pastured until the 10th or 15th of 
June. (G. C. Davis.) 
Contrary to what might be anticipated, the seed-midge neither flies 
far nor is carried far or in large numbers by the wind. Most of the 
midges that emerge in a clover field stay there and lay their eggs there. 
If the wind blows they cling to the clover plants or to the ground, or 
take but short and occasional flights. The direction of flight is, to be 
sure, determined by the wind if the wind is strong, and the midges are 
certainly disseminated more extensively by the wind than by their own 
powers of flight. Nevertheless, the number of midges carried from 
one field to another by the wind is, in the experience of the writer, 
comparatively small. For example, most of the midges in a given 
field of second-year clover on May 25 came forth in that field and 
were the ofifspring of the few midges that entered the same field during 
the latter part of the preceding year. Hence it would seem to be a 
wise procedure to prevent the sporadic heading of first-year clover by 
mowing it back a few weeks after the oats (or other small grains) 
have been harvested, at a time when the growth is vigorous, but yet 
sufficiently early to permit considerable further growth before frost 
sets in. This cutting need not injure the clover. In this state, red 
clover is not infrequently cut in the latter part of the first season, for 
a light hay crop, or to prevent premature seeding, and in the good 
growing season of 1907, some first-year clover hay (mixed with stub- 
ble) was put on the market. This cutting impairs neither the hay 
crop nor the seed crop of the ensuing year, provided it is done early 
enough to allow the plants to recover before winter. Volunteer clover 
should always be cut, as it aflfords a rich nursery for all kinds of clover 
insects. 
Where clover and timothy are mixed, early June cutting will, 
in this latitude, sacrifice the timothy. To obviate this, pasture lightly 
or clip back the growth in May. This treatment, as Webster states, 
brings both the first and the second blooming of the clover too late for 
the destructive work of the midge, and the hay crop as a whole sus- 
tains no loss. 
In a few reported instances, larvae of the seed-midge have been 
found mixed with clover seed in bulk, and the theoretical danger of 
sowing such larvae along with the seed has been pointed out. While 
we have no direct evidence as to the reality of this danger, it would be 
well, on general principles, to kill such larvae, by drying them up under 
a gentle heat, which is said not to injure the seed, or by fumigation 
with bisulfid of carbon.
