Means of control. — When the caterpillars begin feeding on the fniit 

 most of them are about half grown. At this time they are very resistant 

 to poison sprays and it is then too late to do effective work against 

 them. The newly hatched caterpillars are more easily poisoned. Their 

 numbers may be greatly reduced by making one or two applications of 

 arsenate of lead, 5 or 6 pounds in 100 gallons of water, before the blossoms 

 open. In this case one of these sprays will coincide with the first scab 

 spray when the blossoms show pink, and the arsenate of lead should 

 be used in combination with the dilute lime-sulfur. In cases of severe 

 infestation it is important that a poison spray be applied just before the 

 blossom clusters separate. 



ADVANCED READING-COURSES 



Two advanced reading-courses are now offered by the Cornell Reading- 

 Course for the Farm: the advanced reading-course in fruit growing and 

 the advanced reading-course in vegetable gardening. These courses aim 

 to assist persons who desire to make a careful and systematic study of 

 these subjects. They are especially provided for members of the reading- 

 course for the farm who have completed a study of the available reading- 

 course lessons and who are now ready to specialize. A textbook, questions, 

 and correspondence are used in conducting each course. Statements on 

 important questions are prepared by the students, and are graded by an 

 instructor and retiirned with helpful comments and suggestions. This 

 provides an opportunity to have opinions and conclusions that are the 

 result of study or experience, judged and corrected by an expert. The 

 requirement of effort and thought on the part of the student by means 

 of questions, and the returning of corrected papers with the grades, offer 

 to the student some of the advantages of a correspondence course. The 

 only expense connected with the courses is the purchase of the textbook. 

 As this remains in the possession of the student, it may well be looked 

 on as a permanent investment. The cost for the textbook in the advanced 

 reading-course in fruit growing is $1.35, and in the advanced reading- 

 course in vegetable gardening is $1.65. 



The following is an outline of the nature and the requirements of the 

 work given in the advanced reading- courses. The chapters in the text- 

 book are studied consecutively, one at a time. The student's purpose 

 should be to stud}% and not merely to read. Each chapter should receive 

 considerable time and thought. The best results will be obtained by 

 setting aside a definite time each day for the work. After making a careful 

 study of each chapter, clear and concise answers should be made to the 

 questions on it without referring to the text. In general it is expected 

 that the course will be completed within six months. The student should
