strongly the distinctive characteristics of that family. Further trial is 

 needful to properly .determine their relative value. 



Alice, received from T. J. Dwyer of Cornwall, N. Y., in 1896, and Gold- 

 stein, oricjinating in Mississippi, and received from Thompson's Sons of Rio 

 Vista, Virginia, in 1897, appear to be healthy and vigorous, but, of course, 

 are not yet fruiting. 



Campbell Early was received from Geo. S. Josselyn of Fredonia, N. Y., 

 the introducer, who also sent specimens of the fruit when at maturity. 

 The growth of spring set plants, as well as the character of the fruit 

 received, indicate that it will probably sustain the high character given it 

 by its originator, Geo. W. Campbell of Ohio. 



Plants of four varieties, Josselyn No. 5, white; No. 7, white; No. 9, 

 black; and No. 10 (not yet in fruit) were received from Mr. Joeselyn in 

 1891. Theee rank from 8 to 10 in vigor, and the first three appear prom- 

 ising as market varieties. 



Esther and Ecckwood, received from the same source in 1892, are both 

 above medium in quality; productiveness yet undetermined. 



Plants of a seedling originating with Mrs. Mason of Ottawa county, 

 Michigan, were received for trial in 1892, and have now fruited. The 

 bunch is small, compact; berry, dark reddish amber and of fair to excellent 

 quality. 



Victoria, the white variety originated by the late T. B. Miner, was 

 received in 1892 from Geo. W. Campbell of Ohio. A variety under this 

 name, but black in color, has been received from two or three other 

 sources. It is apparently not Ray's Victoria, which is light amber in 

 color. 



PLUMS. —Primus. 



The pruning of plums was commenced on March 20th and continued 

 from time to time as weather permitted. The woik was completed on 

 March 27th. 



Examination by Prof. Taft betrayed the presence of Putnam scale upon 

 several plum trees, on March 31st these being yet dormant were sprayed 

 with kerosene emulsion, consisting of one-fourth kerosene ag applied to a 

 part of the trees, and one-sixth kerosene as applied to others. Owing to 

 strong wind, the emulsion could only be applied to one side of the trees at 

 this time. 



On April 1st and 2d the remaining plums were treated with emulsion 

 consisting of five gallons of kerosene, six pounds of whale oil soap and 

 forty gallons of water. 



On June 26th large nuipabers of aphides were discovered upon several 

 plum trees. These were treated with a strong decoction of tobacco. This 

 so far stupified them that they dropped to the ground, apparently dead. 



They, however, recovered after several hours, and started to resume their 

 attack upon the foliage, but were treated this time with emulsion, com- 

 posed of a gallon of kerosene and a gallon of whale oil soap in fifty gallons 

 of water, which proved effectual. 



July 1st and 2d shot-hole fungus and also brown rot of the fruit appear- 

 ing upon several plum trees, they were sprayed with Bordeaux mixture, 

 using four pounds of copper sulphate and six pounds of stone lime, in fifty 

 gallons of water.
