In this case the Russian apricots have been nearly twice as reliable 

 nnder the existing conditions as the common apricots have, for they 

 have lived 91 per cent, of their possible time, while the common 

 apricots have lived but 47 per cent, of their possible time. The 

 plums have lived 97 per cent, of their possible time, showing a very 

 small mortality, although the list of varieties planted contains some 

 that are commonly considered not very hardy. The tables show 

 that in 1888 a planting of both common and Russian apricots was 

 made. Up to the present time the common apricots which were 

 planted in 1888 have lived 61 per cent, of their possible time while 

 the Russians have lived 94 per cent, of their possible time. 



The total number of common apricot trees which were planted in 

 Station orchard ISTo, 4 from 1884 to 1889, excepting those that died 

 within a year after they were planted and those that were accident- 

 ally injured, is thirty, of which three still live. Making the same 

 exceptions the number of Russian apricots planted during this period 

 is eight, of which six are still living; and the number of common 

 plums is sixty-eight, of which sixty-five are still alive.
