ducks, caught in a depth of water varying from eighty 
to one hundred feet, seventeen miles out in the lake on 
a northwest course from the Erie harbor light. One week 
prior to this date large quantities of these ducks were 
brought in by the boats, and on the day mentioned several 
boats came in with fully as many as the tug Uncle.” 
NOGRESION Vets COCKLEBUR 
E. E. MASTERMAN, NEW LONDON, OHIO. 
In July, 1896, Dr. Claypole, of Akron, Ohio, asked me 
to find how general was the opinion in my locality as to 
whether one seed of the two in the cocklebur grew the first 
year after maturing and the other the second year. 
As opportunities presented, I asked perhaps twenty of 
the older farmers. None of them seemed to know any- 
thing about it except that enough seeds grew to injure the 
price of wool. 
The following year, 1897, when coming home from 
Wooster, Ohio, an old German told me that one seed always 
grew one year and the other some other time. Never both 
at the same time. 
Not long after that I saw a statement of Prof. Arthur’s 
experiments (Ohio Experiment Station Bulletin No. 83, 
September, 1897, page 353), confirming the opinion of the 
old German, since his own experiments had not been able to 
produce two plants from one bur at the same time. 
I then became interested and greatly desired to know 
and test for myself. I gathered a quantity of burs and in 
the spring of 1898 I planted 1,000 burs, of which 917 burs 
grew two plants. In 1899 I planted another 1,000 burs, 
of which g21 burs grew two plants. In 1900 I planted 
another 1,000 burs, of which 913 burs grew two plants. Of 
the 3,000 burs planted in three years 2,751 burs grew two 
plants. Of the remaining 249 burs some grew one plant, 
some did not grow at all, some had two seeds apparently
