NOTES ON THREE SPECIES OF GOPHERS FOUND AT L.^WREXCE, KAS. 



BY PROF. L. L. DYCHE,* .STATE UNIVERSITY. 



I. Ground Squirrel {Spermophilus tridecemlineatus). Rather common. It digs 

 tip corn, squash, melon and other seeds soon after they are planted. Farmers say 

 that these ground squirrels can smell the seeds in the ground, for they always dig 

 straight down to them. Some watermelon farmers report that the squirrels fre- 

 quently stop the growth of a vine by nibbling or cutting off the tender runner near 

 the end. Some cases have been reported where they cut holes in the nearly ripe 

 musk- and watermelons and ate the seeds out. 



II. Ground Squirrel {Spermophilus Franklini). At present not common, except 

 in certain localities in the eastern half of the State. Not much damage done by 

 this species — at least not much thus far reported, except from certain localities, 

 and most of these where fields were inclosed by stone walls or hedges, which gave 

 the squirrels special protection. The squirrels dig up the corn, and sometimes 

 other seeds, soon after it is planted, in the spring. In the fall they do some damage 

 by burrowing under corn-shocks; they eat some of the corn, and usually carry con- 

 siderable down into their burrows. They were very common on my father's farm, (at 

 Auburn, Shawnee county, Kas.,) about fifteen years ago.t They would dig up the 

 corn almost as fast as it was planted for a distance of from fifteen to fifty yards all 

 along the stone walls wherever the latter inclosed the fields. On an average, there 

 could not have been less than one squirrel for each rod of fence; apparently there

t Information from various sources goes to show that this species of squirrel-gopher was very com- 

 mon in many regions of the eastern third of the State about fifteen years ago.
