relatively high, one-fourth being over thirty years old. A number of these 

 old trees go out of production each year, but the recent plantings make up 

 for this reduction. Baldwin plantings during the past fifteen years have been 

 almost as heavy as those of Mcintosh. Over 50,000 trees have been set during 

 the past five years, and the plantings for the five-year period previous to 1920 

 were considerably above this figure. Nearly half of the Baldwin trees are 

 under fifteen years of age, and allowing for the loss of old trees, it is reason- 

 able to expect a 50 per cent increase in the crop during the next fifteen 

 years. The popularity of the Mcintosh will undoubtedly reduce future plant- 

 ings of Baldwins. The Baldwin crop in 1924 was over 50 per cent of the 

 entire crop of the State. 



Mcintosh 



The Mcintosh is the second most important variety grown in the State. 

 Nearly 25 per cent of all trees are of this variety and the percentage is in- 

 creasing each year. Of the 240,000 Mcintosh trees reported, about half are 

 not yet in bearing. Over 90 per cent of the Mcintosh have been planted 

 during the past fifteen years, which means that only a small number of the 

 trees now bearing have reached full production. The heaviest planting occurred 

 from 1915 to 1920, an average of 18,000 trees being planted per year. The 

 present annual rate of 10,000 trees indicates a 40 per cent decline from that 

 period. The average age of the bearing Mcintosh was twelve years in 1925. 

 As these trees mature in the next ten or fifteen years their production will be 

 greatly increased. In addition, about 120,000 young trees will come into full 

 bearing during this period. This estimate includes no new plantings and 

 allows for a loss of 25 per cent of the present young trees. The production 

 of Mcintosh in 1924 was slightly over 200,000 bushels, about one-seventh of 

 the total commercial crop. Since the 1924 season was a poor one for Mcin- 

 tosh, this figure is below the average crop. 



More grading is done on the Mcintosh than on any other variety, approx-
