average over 50 barrels in a series of years. The average acre yield is some- 

 what larger in Wisconsin than in Massachusetts, but elsewhere it is less. 

 The differences are due partly to differing natural conditions for the in- 

 dustry and partly to methods of culture. All of the cranberry liogs in Mas- 

 sachusetts and most of those in Wisconsin are covered with sand. Less 

 than a sixth of the New Jersey acreage is sanded. Most bogs in Massachu- 

 setts are kept free from weeds, wiiile most of those elsewhere are very 

 weedy. 



The table giving the cranberry production in tiie three chief growing 

 regions since 1900 shows the lead this State has in the industry. Our 

 natural conditions for this crop are so good that this lead will be held a 

 long time. The relative lack of suitable and accessible sand is a handicap 

 elsewhere. The New Jersey climate is rather unfavorable, promoting weed 

 and fungous troubles more than those of other cranberry districts. Wis- 

 consin is well placed in the industry and may be a long-term rival 

 in spite of its troubles with drouth and summer frosts; its geographical
