the larva'. Cliiulxd u[i and secured tlie punctured scales for 

 my collection. At this rate how many mi^ht a woodjM'C'kcr 

 eat in a year? Wish I could follow him and discover iiow 

 many he actually destroys in a day. Put niai row hones and 

 suet in the apple trees to attract woodpeckers to the orchard.

April 12. Hunted one hour again for larvae; found only 8, l»iit 

 have observed the woodpeckers working on the trees all 

 winter, and counted 17!» [»unctured bark scales from which 

 the larvae had been removed. Those found were still in the 

 larval stage. 



May 1.5. Apple trees in bloom. Hunted one-half hour: found 

 1 larva and 2 ])U]>a' (Lab. liook. p. 42). 



June 11. A[tples about the size of marbles. 8 v.m., hung a lan- 

 tern in a tree where apples were thickest. Caught a moth 

 in act of laying an egg on an apple. As I raised my net to 

 catch another, a bat flitted by and snai>ped it. Tried to 

 catch bat but he was too quick for uie. 



The main laboratory for this course is the out-of-cloors, — 

 the yard, garden and orchard, streets and roadsides, pastures, 

 fields, woods, streams, lakes, hills, and s\\ani[)s. Thousands 

 of interesting things are happening out there all the while, and 

 it is there the student must go if he would really U-arn his 

 lessons. AVith definite assio*nments of what to seek or to study 

 and observe, most of this field work should ])e done either 

 singly or in small groups of two or three. In addition to 

 this tliere should l)e individual [)robk'ni-woi-king and lesson- 

 learnhio" fur discussion and demonstration of the nu)re ueneral 

 problems, such as the study of habitats: tlie struggle for life 

 as seen in a dense woods; the distribution of a number of 

 the types studied in the course; migration of birds; recog- 

 nition of trees, birds, conunon plants. A numlu'r of s})ecial 

 field tri})s also should be ari-anged. The success or failure (d' 

 these will depend upon the teacher's know ledge of the locality
