ON PAPER-SHELL WALNUTS 



tant article of commerce. But there are great pos- 

 sibilities open to it if the shell could be reduced 

 to a condition comparable to that of the English 

 walnut. 



The nuts borne by the Paradox are interme- 

 diate in form and appearance between the types 

 of nuts of its parents. Exteriorly they resem- 

 ble the Persian walnut, but the shell partakes of 

 the thickness and solidarity of that of the black 

 walnut. In at least two instances among the thou- 

 sands of second generation Paradox walnut trees 

 that have been grown, the trees produce extra 

 large fine walnuts in abundance. However, both 

 of these are quite thick-shelled, but from their 

 second generation hybrid, which can be multiplied 

 abundantly, good, hardy, thin-shelled varieties 

 may be produced. 



It is possible that further hybridizations, in 

 which the Royal and Paradox hybrids were them- 

 selves crossed, might result in the development 

 of a variety, properly selected, that would retain 

 the good qualities of the Persian nut, and combine 

 these with the size and prolific bearing of the 

 Royal. 



HYBRIDIZING METHODS 



The experiment, at any rate, is well worth try- 

 ing. But, of course, whoever undertakes it must 

 be content to make haste slowly, for the black wal-
