added to either of these in order to control the curculio. The first appli- 

 cation should be made one day before the blossoms open, and a second 

 application should be made when the young fruit is set. If the disease 

 has not been controlled by previous applications a later spraying may 

 occasionally be necessary; this should be applied at least ten days before 

 the time for picking. The arsenate of lead should be omitted if this 

 spray is applied. 



Leaf spot {Cylindrosporhim padi) . — This is a fungous disease which 

 causes the leaves to become thickly covered with reddish or brown spots 

 and to fall prematurely. This greatly impairs the vitality of the trees 

 and winterkilling sometimes results. 



Control.' — The spraying recommended for brown rot will usually 

 control this disease. If very serious, however, two more applications 

 of bordeaux mixture may be necessary. The solution should be applied 

 at intervals of two weeks. 



THE CORNELL READING-COURSES 



The Cornell Reading-Courses are two in number — the Course for the 

 Farm and the Course for the Farm Home. The purpose of these courses 

 is to assist persons who desire to learn but are unable to leave their work. 

 They are not correspondence courses in the usual sense, but are a means 

 of interesting readers in elementary agricultural subjects and important 

 farm, household, and general rural problems. They also aim to lead the 

 reader to express his opinion and discuss his own experience. The Read- 

 ing-Courses are free to residents of New York State. 



Course for the Farm. — The Reading-Course for the Farm is planned to 

 assist persons who desire to read reliable agricultural literature. Enroll- 

 ment in this course is by the following subjects: the soil, poultry, rural 

 engineering, farm forestry, the horse, dairying, fruit-growing, farm crops, 

 stock-feeding, vegetable gardening, plant-breeding. A series of lessons 

 on each of these subjects is in progress. Twenty-five lessons are at present 

 available and the number is increased by the publication of a lesson each 

 month. Each lesson is accompanied by a discussion paper containing 

 questions on the important points in the lesson. If the discussion paper 

 is returned by the reader it is read carefully, a personal reply is made 

 when information is requested, and another Reading-Course lesson in 

 the same series is sent if available or references for advanced reading are 

 given if desired. In this way individual attention is given to every reader, 

 to the end that consecutive instruction may be received by him. New 

 lessons on the subjects selected are sent as they are issued. It is hoped 

 that the discussion paper may be a means of personal contact between
