Hume: As this finishes this section of 
the program, I think we better take a few 
minutes for any questions in regard to 
Mr. Kramer’s paper or the one presented 
by Mr. Rogers. 
Sadler: Can the ground be satisfac¬ 
torily cultivated in old groves with a 
tractor ? 
Kramer: Yes, there are extension acme 
and disc harrows which may be used for 
cultivating not only in the middles but 
out under the branches and right up to the 
trunks. The harrows should be arranged' 
or built so as not to interfere with the 
branches.
