PEACH AND THE PEAR. 323 



Question 6. I do not know that pears will kill, 

 unless trees are killed by low temperature, nor do I 

 know how low. 



Question 7. First of May. Eight inches. All 

 orchards should be ploughed that depth ; once is suf- 

 ficient, I harrow across the balance. I go over with 

 duck bills and flukes ; once a week is not too often, and 

 as long as you can get under the tree. 



Question 8. Bone and potash, either Fall or Spring. 

 From four to six hundred pounds per acre. If I get my 

 potash from Kainit, I throw from wagon with shovel, but 

 if I use a more concentrated form, it must be spread 

 broadcast, by hand, or with spreaders made for the 

 purpose. 



Question 9. Springs just before they bloom. If 

 trees are pruned just before they bloom, a careful pruner 

 will cut out enough bearing wood so that the remaining 

 fruit will mature. 



Question 10. Too much lime and pound manure. 

 Fertilizer described in No. 8, will check it. 



Question 11. No. 



Question 12. Yes ; no ; road dust, air slaked lime 

 or plaster, either will answer to kill them. 



Question 13. No.
