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.

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-
