Yields 



The average annual acre \ield of cranberries in this State ranges from 21 to 

 41 barrels, but well-managed bogs with proper facilities probably average over 

 50 barrels in a series of >ears. The average acre yield is somewhat larger in Wis- 

 consin than in Massachusetts, but ehewhere it is less. The differences are duo 

 parti}' to differing natural conditions for the industry and partly to methods oi: 

 culture. All of the cranberry bogs in Massachusetts and most of those in Wis- 

 consin are covered with sand. Less than a sixth of the New Jersey acreage is 

 sanded. Most bogs in Massachusetts are kept free from weeds, while most ot 

 those elsewhere are very weedy. 



The table giving the cranberry production in the chief growing regions since 

 1900 shows the lead this State has in the industry. Our natural conditions foi 

 this crop are so good that this lead will be held a long time. The relative lack of 

 suitable and accessible sand is a handioip elsewhere. The climate is rather un 

 favorable in New Jersey, promoting more weed and fungous troubles than h\ 

 other cranberry districts. Wisconsin is well placed in the industry and may be
