3. First fruit ripe. 



4. All leaves, or more than half of them, colored. 



Typical and average plants should always be ^selected for 

 observation, and they should be few in number. A dozen well- 

 selected species will afford more satisfactory records, year by 

 year, than observations made at random upon a great variety of 

 plants. For the sudden moods of spring, the peach and dande- 

 lion are useful for observation, but such plants — those which 

 respond quickly to every fitful variation of the early season — 

 are not reliable for the staple records of the years. Useful 

 plants for study are the following ; 



Apple. 



Pear. 



Quince. 



Plum. 



Sweet Cherry. 



Sour Cherry. 



Peach. 



Choke Cherry. 



Wild Black Cherry. 



Japanese or Flowering Quince. 



Cultivated Raspberry. 



Cultivated Blackberry. 



Cultivated Strawberry. 

 Lilac. 



Mock Orange or Syringa. 

 Horse Chestnut. 

 Red-pith Elder. 

 Common Elder. 

 Flowering Dogwood. 

 Native Basswood. 

 Native Chestnuts. 

 Privet or Prim. 

 Red Currant. 

 Cultivated Grape.
