lesson, because the disc florets are small and probably at this 

 season have finished blooming. Omit obs. 3, p. 555. 



The ladybird — At this time of the year 

 the ladybird beetles are crawling about 

 to find cozy places in which to pass the 

 winter. These kind little friends who 

 help us so much in the garden deserve, 

 careful study. For a lesson on the lady- 

 bird, use obs. 1, 2, 3, 4, 5, p. 415. The 

 story of the larvse should be told (p. 414) 

 in such a way, and pictures should be 

 shown (p. 415) that the pupils' interest 

 will be stimulated in this useful insect.

The Colorado potato beetle — This may be found in any potato 

 patch in October by digging in the ground around the potato hills 

 or in looking under rubbish around the fields. Often indeed a few 

 chance planted potato vines are still green and the orange larvae 

 may be found industriously feeding. This insect may be studied 

 as a beetle type. For a lesson on the beetle, use obs. 2-5, £.411-12. 

 Its method of self protection may be told in a story, p. 49, and 

 studies by using obs. 6, p. 412. The story of the marvelous march 

 of beetle hordes from Colorado eastward to the sea, should be given 

 as an exercise in English.
