observed in the lawn their injurious work is at once stopped. They 

 will be found just below the sod if they are responsible for its con- 

 dition. 



In this connection the following letter from E. J. Phelps, of 

 Minneapolis, under date of Oct. 13, 1908, is of interest : 



"Replying to your favor of the ninth, would say that in the summer of 

 1899 my lawn at the Lake was ruined for that season by the grub to wh^ch 

 you refer. I do not remember now that we took any means to destroy them 

 excepting to have the turf taken up and the grubs picked up by hand and 

 put in a pail and destroyed. I should imagine that we gathered one or two 

 bushels of them. 



"As 1 remember it, we were not troul:)led the next year and I have seen 

 no trace of them since. I understand that a number of the places about 

 the Lake were injured this year, but so far our immediate neighborhood is 

 fortunate enough to escape their work. 



"I have not used any fertilizer upon the lawn, but have almost every year 

 drawn a good many loads of black dirt which has been scattered over it. 

 and in this way have kept the lawn in good condition. 



"This trouble referred to in 1899 I did not notice before departing for 

 the East the latter part of June. When I returned about a month later the 

 sod looked white and burnt out and I at first supposed that it was due to 

 inattention on the part of the gardener, but later discovered the real cause, 

 as it was very easy to kick the turf up or to pick it up and lay it back in 

 quite large sections or strips, leaving the colony of grubs exposed licneath."

Figs. 74 and 7S do not represent fossil monsters of prehistoric 

 times, but are two white grubs attacked and killed by a fungus growth 

 (seen growing from near the head of the grub in each case) sent the 

 entomologist bv ^Ir. ^L C. Clark, of Nymore, Minn., with the state- 

 ment that one-lialf of his potato crop had been eaten by this pest.
