482 ANNUAL REPORT OF THE * Off. Doc. 



These are actual results aud methods on one specific and thor- 

 ough case of orchard renewal. We have seen them proportionately 

 successful elsewhere. Additional measures, including top-working, 

 must be taken where the varieties are unsatisfactory in addition to 

 being unproductive. It is desirable to start the renewal operations 

 at the close of the full year in order that trees may accommodate 

 themselves to the new order of things in the off year and be ready 

 for increased bearing in the next full year. 



A specific plan for doing this work of renewal on two Pennsyl- 

 vania orchards has been prepared but includes too much detail for 

 rehearsal here.
