    A mixture of Arasan 75 and Endrin 50W was tried in two concentrations on acorns of Shumard oak ( Quercus shumardii) and swamp chestnut oak ( Q. michauxii) to determine its effectiveness in protecting acorns from damage by gray squirrels ( Sciurus carolinensis) and cotton rats ( Sigmodon hispidus). Treated and untreated acorns were exposed to 12 gray squirrels and 12 cotton rats in a series of cage tests. The repellent was effective against both squirrels and cotton rats when untreated acorns were also available. It was quite effective against cotton rats, but not against squirrels, when only treated acorns were available. In periods of abundant alternate food supplies, a direct seeding of treated acorns should produce a good stand, but this may not be true under adverse food conditions.
