At the drug-testing garden at Madison, Wis., observations similar to 
those at Arlington have been made for two years, and the results are 
given in Table IV. The first nine plants were under observation in 1911 
and 1912, while the last eight were sent to Madison from Arlington as 
young seedlings in the spring of 1912. No notes were taken of the indi¬ 
vidual plants with regard to height, spread, and number of stems, since 
they were all very much alike. Each plant acquired a height of about 
2 feet and had an average of three or four stems each. 
The stages of growth at which these pickings were made correspond 
closely to the first, second, and third pickings at Arlington, irrespective 
of the dates. Since Madison is farther north than Washington, the plants 
came up later in spring than in the vicinity of Washington and did not 
reach the full flowering stage until in July or early in August.
