APPLE ORCHARD SURVEY OF NIAGARA COUNTY. 289 



Age and yield. The period of maximum production seems to come 

 between fifty and sixty-five years after planting. Some orchards or 

 parts of orchards were seen, which were planted previous to 1830, but 

 no accurate data could be given of the yields so they were not used 

 in this computation.

The comparatively high yield for the last two periods, namely, 1885- 

 89 and 1890-94, is due to the fact that these orchards were mostly 

 of the Oldenburg (Dutchess) variety, which is an early bearer.
