 let some one percent household ammonia stand in the sprayer over night. Be sure 

 some is run through the hose and nozzle,

TOBEY'S TRAVELS - Chapter X 



As we left Medford, Oregon in a down pour and headed for "sunny" California, 

 we fully anticipated that the STjn would be shining as soon as we reached the state 

 line. But, alas, we were due for disappointment. However, apparently remorseful 

 that California should have greeted New Englanders so discourteously, the clouds 

 suddenly parted, the sun shone for about ten minutes and then we travelled in the 

 rain for several more miles on our way to Davis which was our next objective. 



The College and Experiment Station at Davis is the Agricultural branch of 

 the University of California with the main campus at Berkeley. The Davis campus, 

 consisting of 3000 acres is one of eight connected with the University of California. 

 At many of the other branches there is an experiment station only and thus no student 

 enrollment. Dr. Stanley Freeborn, a graduate of the Massachusetts Agricultural College 

 in the class of 19lU had recently been appointed Provost at the Davis Campus, 



On our arrival at Davis we were fortunate to find Dr. Warren P. Tufts, Head 

 of the Department of Horticulture, in his office and to obtain from him considerable 

 .information concerning the horticulture of California and in addition a personally 

 conducted tour of the Campus and experimental grounds. 



It would r equire much more space than is available in this publication to 

 describe completely the vast pomological enterprises in California, Consequently, 1 

 shall attempt to mention only a few of the most signigicant items a« gleaned from 

 Professor Tufts and other sources. 



At Davis the average annual rainfall is l6 inches coming mostly in December, 

 Jari uary, and February, The normal minimum temperature is 22 degrees Fahrenheit, In 

 1932 a minimum of 1^ degrees Fahrenheit killed the lemon trees and seriously injured 

 orange trees. 



While many interesting experiments are being conducted at the Davis Experi- 

 mental Station one outstanding discovery is particularly worthy of note. 



For some years pear growers have been troubled with a disease known as 

 Black End, This was found to be due to an incompatibility between stock and scion.
