Phoma mall, and has completed an extended study of the cultural 

 characters of these two fungi on different culture media. In addi- 

 tion to these fungi, others associated with these plant diseases are 

 studied to determine their relationships and to work out the life 

 history of each. In connection with this work it has been found 

 that certain fungi, either not described or hitherto not considered, 

 are of economic importance. 



The Hatch work of the station included a careful study by the 

 entomologist of a remarkable outbreak of the saddled prominent 

 {Heterocampa guttivitta) and the results of this work are fully re- 

 corded in a bulletin published during the year. The true sexes of 

 Pemphigvs tesseUata were discovered for the first time, the alternate 

 host for the species ascertained, and the identity of I\ (werifolii 

 as the same species established. These results have been partly pub- 

 lished in other than station publications. 



The vegetable pathologist found it inadvisable to apply even small 

 quantities of lime to Aroostook potato soils on account of the result- 

 ing increase in potato scab. He made the observation that the 

 crotch injury of apple trees in Maine is a form of winter injury and 

 is not caused by Bacillus amylovorus ; and further it was ascertained 

 that self-boiled lime-sulphur mixture is of value as a preventive of 

 apple scab, but is not as efficient as Bordeaux mixture. These results 

 have all been published in bulletin form. Weather records with refer- 

 ence to winter injury of fruit trees show as a general rule for that sec- 

 tion a fairly well-defined minimum temperature below which certain 

 varieties of apples can not endure. Less danger is found to result 

 from continued low temperature than from abrupt changes from 

 mild to low temperatures. 



The inspection work of the station is kept quite distinct from in- 

 vestigational duties. 



The following publications have been received during the year: 

 Bulletins ir)8. Food of num studies; 159, Appliances and methods for 

 pedigree poultry breeding; 160, Fertilizer inspection; 161, The sad- 

 dled prominent: 162, Insect notes; 163, Finances, meteorology, in-

 Inheritance of fecundity; and 167, Field experiments, 1906-1908.
