merit in respect to each point on the score card. In judging corn take a five- 

 ear sample and place the ears in the order of merit in respect to each point. 



Step 3. Score and judge the exhibits. After the judging is completed 

 discuss the placings and clear up anything not understood. 



It is well to have one or two exhibits which will score high. The other 

 samples should show clearly most of the strengths and weaknesses indicated 

 by the score card. The instructor needs a large amount of material to select 

 from. In judging grains it is well to have at least one quart of each sample 

 to be judged. More than one student may then work with a sample and the 

 weight per bushel may be figured with fair accuracy. 



A corn or potato show will nicely supplement judging work in these crops. 

 The show should include a judging demonstration and a program to create 

 interest in crop improvement. 



3. Field Trips. The following notes are taken from a lecture by Professor 

 W. F. Lusk of Cornell University. 



(a) Field trips should be considered as a necessary outgrowth of teach- 

 ing and should not be organized merely for the sake of having a field trip. 



(6) A field trip should have a definite aim. 



(c) The number of field trips should depend upon the need and what the 

 community has to offer. 



(d) The teacher should have in mind the means of realizing his aim and 

 the preparation on his part should be made with the same care as for inside 

 laboratory work. He should go over the ground first. Failure to make care- 

 ful preparation will be more fatal to success than with inside laboratory work. 



(e) The class should be prepared by the presentation of specific informa- 

 tion which will enable the students to appreciate the points presented on the 

 trip. The teacher should raise questions which the field trip will answer. 



(/) Do not attempt to do a job lot of teaching which has accumulated 

 or dissipate the energy of the class over other subjects at the expense of the 

 main aim. 



(g) It is well to use the question and answer method to bring out the 

 points of the lesson on the trip. As far as possible make the students think 

 out the points. 



(h) The lesson of the trip should be summarized by a later class discussion 

 and generally by means of a notebook. 



Diseases and Insects Affecting Farm Crops. In a majority of cases, the 

 entire newness of the subjects of plant pathology and entomology to the 

 student and the lack of training for these subjects on the part of the instruc- 

 tor makes it impractical to go far into these subjects. In many schools the in-
