If, then, Cer . Greggjl is scrafted, then another phenomenorr 

 appears. The original spines fall off too, but on the stems, where 

 they had beert, entire bundles of new spines- appear after years, which- 

 increa.se each year in Fall, and these spines are entirely different 

 from the earlier oness namely to one inch long, entirely straight, , 

 and very Sharp* This appearance is evident with Ce-.Gre^rii al - 

 ways after a few years ( I posess k such specinens) , but not so with
