little expense by again covering with sand. A light 

 covering of sand every five years would probably give 

 satisfactory results. It is found in some cases that 

 a light dressing of superphosphate will give the plants 

 a vigorous start and greatly improve the yield and 

 quality of the fruit. 



INJURIOUS INSEOffS 



Two insects have become somewhat of a menace to 

 the cranberry crop — the "leaf roller" and the berry 

 moth. The former is prevented from doing serious 

 damage by flowing for a few days or a week soon after 

 they begin to work seriously. The berry moth is more 

 or less destroyed by the use of arsenate of lead sprayed 

 upon the plants and fruit while quite small. For 

 further particulars as to controlling insect pests, see 

 bulletins of Massachusetts and New Jersey experiment 

 stations. 



Many varieties of cranberries are now being grown. 

 They may be divided into three groups, i. e., the Bell, 

 Olive and Bugle types. Figure 90 shows the large 

 Bell varietv.
