NOTES ON PLUMS 
(From the Special Report of the American Pomological Soc.) 
The committee in charge of this department of the Report, com¬ 
posed of F. A. Waugh, U. P. Hedrick, C. L. Watrous, and J. W. Kerr, 
state that important changes have been going on in the standing of 
the different classes of plums, though no such revolutionary occurrences 
have taken place as the introduction of the Japanese varieties some 
years ago. The most important changes relate to the localization of 
the different classes and varieties. It is pointed out that a class which 
is successful and popular in one section may be quite otherwise in 
another. The American plums appears to be at best for Iowa, Wiscon¬ 
sin, and the neighbor'ng states. The Domestica plums, including the 
Damsons, appear to be best for southern Michigan, New York State, 
Massachusetts, and Connecticut. Plums of the Hortulana class, of 
which Wild Goose is a prominent member, appear to be most profitable 
in southern Jersey, Delaware, and the Maryland peninsula, while in the 
Southwest those of hybrid parentage, combining perhaps Japanese and 
Hortulana blood, succeed best. The Japanese varieties continue to be 
planted extensively over a wide range of territory. They are vigorous, 
productive, the fruit is handsome and carries well. The trees, however, 
are not long lived. Among the varieties which have not grown in 
popularity in the East are the Wickson, the Climax, and Simoni. The 
main fault with these is lack of productiveness. 
In the marketing of plums, the Climax baskets are used most 
extensively, except on the Pacific Coast, where the crates or carrier 
package is in more or less universal use. 
CO-OPERATION 
Important .Work of the Root Gall Committee 
By Chairman Smith 
Mr. E. A. Smith of the Jewell Nurseries of Minnesota is 
following up his excellent work in prosecuting root-gall 
investigations by urging the necessity of establishing experi" 
ments .in all parts of the country in order to secure such 
a mass of facts as may be considered conclusive to this end 
Mr. Smith urges cooperative experiments in the following 
letter: 
Dear Sir: 
A year ago at the National Convention at Denver, the 
writer was appointed chairman of what is known as the 
Root Knot Committee. You were kind enough to act as a 
member of this committee, and we appreciate your cordial 
support and prompt replies to our various letters. 
The writer has been appointed chairman of this Root 
Knot Committee for the coming year. Considerable interest 
was manifested in this subject at the meeting recently held 
at St. Louis. Some articles were presented by different 
members of the Committee which will be reviewed and 
referred to later on, there not being time at the Convention at 
St. Louis. 
Several members of the Committee reported that the 
agitation started a year ago has been a benefit, as it furnished 
information to inspectors who wanted to do what was right 
but really had little to guide them. Except in a few cases 
inspectors were more lenient in their inspection of apple 
trees, on which there was Root or Crown Gall, than pre¬ 
viously. But there remains much to be done. 
We make the following suggestions: Let every nursery¬ 
man set out apple trees, which have Root Gall upon them, 
take photographs of some of them when the trees are planted. 
Some of our members are doing this. As time goes on you 
will have done something definite and will secure a data to 
work from. The experiments will be valuable. If work of 
this kind had been done twenty years ago there would be 
very little Root Gall scare now. Remember, we are doing 
work that will be of special value ten, fifteen and twenty 
years from now. Report if you are able to do some experi¬ 
menting along this line. 
If you can interest other nurserymen to do the same 
thing, all the better. It is also necessary to get Experimental 
Stations to do some work by planting out a hundred trees, or 
more. If you do the same thing, and do the work just as 
well, the result of your experiments will not have the same 
weight as the same work done by the Experimental Station. 
They carry authority. Now, if you can interest the Experi¬ 
mental Stations in your state to do some of this work, you 
will render valuable service to the nurserymen of the entire 
coimtry. 
If as chairman of this Committee, I can render you any 
assistance, or can write parties regarding this matter, who 
have Experimental Stations in charge, advise me and I 
shall be pleased to do what I can. Any items of interest 
along the line of Root Gall Experiments or of inspections, I 
shall be pleased to have you send me direct. I wish to 
gather all the information possible, then condense it and 
either report it to the Association, or hold it on file for future 
reference. Remember, this work is far reaching. It is not 
for the individual, but the country at large. 
We also desire committees in the following states, where 
we were unable to secure them last year. If there is anyone 
you can recommend, kindly do so. Alabama, Idaho, 
Massachusetts, Colorado, Michigan, Virginia, New York. 
Following is a list of chairmen of Committees already 
appointed: California, Geo. C. Roeding, Fresno; Georgia, 
L. A. Berckmans, Augusta, Georgia, C. T. Smith, Concord;
