but these have not been sufficiently tested as yet to make a 
recommendation. 
We have noticed here that the white clover is not attacked by 
the grubs, and this observation is borne out by the observations 
of others in various states. We will therefore plough up portions 
of the lawn most badly affected and sow them in white clover 
as quickly as possible, about three quarts of seed to the acre, 
then top-dress with well-rotted manure after the ground is 
frozen. The white clover is hardy, thrives well on sterile or 
rocky soil, and makes a very fair lawn without an admixture 
of grass. Ifitis true that this clover is not attacked by the white 
grub, the larvae now in the ground will die for lack of food and 
those already in the pupa stage will emerge as mature insects 
and fly away, probably not depositing their eggs in the clover. 
After the ground is free from insects, grass seed may be sown 
in the clover late in the year, and it will work into the ground 
during the winter and germinate the following spring, resulting 
in the usual lawn of mixed grass and white clover. 
Where lawns are not conspicuous, it might be well to grow 
red clover or alfalfa upon them for a time, cutting off the hay 
for a season or two, then ploughing and sowing the usual lawn 
mixture of grass. In this way, the soil would be much improved 
and the grubs exterminated.
