NOTES ON CERTAIN EXPERIMENTS AND OBSERVATIONS AT THE 

 IOWA EXPERIMENT STATION 



By C. P. Gillette. 



TO PREVENT SQUIRRELS FROM PULLING CORN. 



A series of experiments in treating corn with various substances to 

 prevent its being taken by the striped squirrels were carried on at the 

 Iowa Experiment Station, last spring. The corn was treated in the 

 following manner: Smoked with meat in an ordinary smoke-house until 

 the kernels were black ; smoked in a barrel with tobacco dust; smoked 

 over night in strong decoctions of tobacco and of quassia chips; soaked 

 in a dilute carbolic acid mixture, in strong alum water, in salt water, and 

 in kerosene. The squirrels would take the corn treated in any of these 

 ways, thou^ the carbolic acid treatment and the smoking with tobacco 

 made the corn distasteful, and when in the vicinity of other grain would 

 be left till the last. The best remedy seems to be to harrow the ground 

 immediately after planting to cover the planter tracks, and then to 

 scatter corn about the border of the fields and in the vicinity of the 

 squirrel holes as soon as the corn begins to come up. 



KEROSENE EMULSION AS A SHEEP DIP. 



An 8 per cent, kerosene emulsion was used, in which to dip the sheep 

 on the college farm the past summer, and it was fully proven that a 

 good emulsion can be safely used for this purpose, even when sheep 

 have considerable wool upon their backs. As the kerosene emulsion 

 is much cheaper than the commercial sheep dips, this seems to be a mat- 

 ter of considerable importance to sheep growers.
