EXPERIMENT STATION BULLETINS. 809 



Burbank Nos. 2 and 11 are understood to have originated with that noted 

 experimenter, Luther Burbank of California. They have blossomed here 

 the past season but have not fruited. 



Cheney, Cook, DeSoto, Forest Garden, Forest Rose, Golden (Beauty), 

 Hawkey e, Jewell, Maquoketa, Miner, Moreman, Pottawatomie, Prairie 

 (Flower), Rollingstone, Van Buren, Weaver, and Wolf are all more or less 

 generally known and valued, at the north and west, where the finer eastern 

 varieties fail. 



Kingston and (White) Nicholas have had but a short and imperfect 

 trial here and have not yet shown their qualities sufficiently for character- 

 ization. 



Marianna is far better known for its ability to root readily from cuttings 

 and afPord a supply of stocks for the nursery than for its value as a pro- 

 ducer of fruit. 



Robinson proves to be a vigorous grower and has, the past season, pro- 

 duced a fine crop of good-size, pleasant-flavored fruit quite superior to 

 most if not all the native western varieties that have so far fruited here. 



Simon (Prunus Simoni of nursery catalogues), has now fruited here 

 profusely; the large, bright colored, very peculiar fruit, as grown here, is 

 far from agreeable in flavor. Botanists seem to consider it a sort of 

 Ishmaelite among plums, having specific characteristics peculiar to itself. 



PEARS. (Pyrus communis.) 



The unprecedented drouth of the past season had, apparently, little 

 injurious effect upon the pear, perhaps on account of the deep rooting 

 habit of the species. 



The spray of Bordeaux, given late in the autumn of 1892, was followed 

 on June 12, 1893, with a spray composed of 4 lbs. copper sulphate, 3 lbs. 

 lime, and 2^ oz. Paris green in 32 gallons of water. 



On June 28 the pears received a spray of kerosene emulsion, applied to 

 subdue the slug {Eriocampa cerasi). 



On July 10 to 13 a final spray was applied, consisting of 2 lbs. copper 

 sulphate, 1^ lbs. lime, and 24 oz. Paris green in 32 gallons of water. This 

 application, which injured the foliage of peaches, plums, and cherries, 

 occasioned no perceptible injury to that of pears. 



The blight which, late in 1892, ruined a few pear trees, has again 

 appeared this season, upon a tree of Seedless (Bessemianka), which, when 

 discovered, were promplty ciit back to apparently healthy wood. Indica- 

 tions, however, point to its probable reappearance next season. This 

 appearance of blight in two successive seasons, in both cases upon Rus- 

 sian varieties, may be supposed to indicate a special liability to such 

 attacks. Since both were standing upon rather moist soil, this might be 

 supposed to have induced the attack, but for the circumstance that they 

 were alternated with Bosc, Anjou, and Mount Vernon, which remain in 

 obviously healthy condition. 



The foliage of the pears has been exempt from leaf spot (Fusicladium 

 dendriticum) (which attacks both foliage and fruit of the apple and pear), 

 except that three or four trees of Jones and Mount Vernon pears (which 

 perchance may have been omitted in the spraying), have been seriously 

 attacked.
