EXPERIMENTS IN CARNATION 

 GROWING BY THE U. S. DE- 

 PARTMENT OF AGRI- 

 CULTURE. 

 Read before the .\inericaii ('atnatlon Society 

 Dr. Beverly T. Galloway, Chief of 

 the Bureau of Plant Industry, in his 

 address before the Society called at- 

 tention to the experiments and tests 

 of various kinds connected with the 

 growing of carnations which Iiave been 

 carried on by the Department of Agri- 

 culture for several years. He stated 

 that the work had for its object the 

 securing of information on the follow- 

 ing points: 



1. The relative yield and vigor of 

 plants grown under glass all summer 

 as compared with plants of the same 

 variety grown out of doors during the 

 summer season anil moved to the 

 benches in the u.sual way and at the 

 usual time. 



2. Fertilizer tests to determine the 

 value of different fertilizers alone and 

 in various combinations on vigor aim 

 yield. 



3. A study of hereditary tendencies 

 in so far as same may affect contin- 

 uous vigor and healthfulness and 

 yield. 



.5. The securing of new and desira- 

 ble types by crossing. 



5. A study of fundamental ques- 

 tions of breeding with a view to se- 

 curing data that will be of value to 

 carnation growers and others in the 

 improvement of their crops. 



6. A study of diseases and means 

 of preventing the same. 



Dr. Galloway took up the subjects 

 in the order given, using a table or 

 chart large enough to be seen by all 

 present, to illustrate the results of ex-

periments conducted during the sum- 

 mer of 1906 and the winter of 1907, 

 to determine the relative yield of field 

 and indoor grown plants. He ex- 

 plained how the experiment had been 

 conducted, namely, that plants were 

 propagated from stock of four varie- 

 ties, care being taken to iiaye the 

 stock of as nearly equal vigor and 

 productiveness as possible. Four 

 benches in the greenhouse were given 

 over to the work, each holding about 



1000 plants and the same were planted 

 with stock from 3-inch pots, two rows 

 the entire length of each bench be- 

 ing reserved for the plants grown out. 

 of doors. Dr. Galloway stated that 

 the field grown plants were given the 

 usual treatment and produced fair 

 average growth, but were not as 

 large as those grown on the benches 

 when brought in in September. 



He stated that the results, as show.'i 

 by the chart, were, without exception.
