574 EXPERIMENT STATION KECORD. 



iilants o1:itained had a much more dwarfed form and resembled neither parent. The 

 avthor's experience with hyl)rid poppies is stated to differ from that of Gordon in 

 that the individual plants of the first generation of hybrids differed widely from each 

 other instead of l)eing fairly uniform, as has been the ease in Gordon's work. 



Experiments with phloxes and their allies, B. D. Halsted {New Jersey Stas. 

 Rpi. 1901, i^p. 4^^-424).— Lists are given of phloxes, cobpeas, gilias, and polemoniums 

 grown. 1 1 was noticed that the phlox plants as they grew older contained many green 

 forms. These plants had flower clusters with the bracts much prolonged and oval- 

 shaped. The corollas were -with long tubes and the lobes not fully expanded, giving 

 a half open appearance to the bloom. 



Experiments with ornamental plants, B. D. Halsted {New Jersey Stas. Rpt. 

 1901, pp. 4^1,422). — Notes are given on the following plants grown at the station: 

 Chrysanthemums, peonies, Japanese redbud, hibiscus, cannas, nasturtiums, mignon- 

 ette, petunias, and verbenas. A hardy type of chrysanthemum which has been 

 growri at the station for several seasons was this year attacked for the first tinie by a 

 rust. Japanese redbud has proved too tender for the cold winters and hot summers 

 prevalent in New Jersey. 



Experiments with lawn grasses, B. D. Halsted {Ne^v Jersey Stas. Rpt. 1901, 

 p_ ^j/).— Nine plats of lawn grass were seeded at the station in 1896. A record is 

 given of the percentages of the different grasses for each of the years up to 1901 for 

 each plat. The highest percentages of the original grasses sown are found in the 

 Rhode Island bent grass, Kentucky blue grass, and wood meadow grass {Poa nemo- 

 ralis) plats. 



FORESTRY. 



The Western hemlock, E. T. Allen ( U. S. Dept. Ayr., Bureau of Forestry Bid. 

 33, pp. 53, pis. 13). — An attempt is made to remove the prejudice which has hitherto 

 existed toward the Western hemlock {Tsitga heterophylla) by pointing out its uses, 

 economic value, and conditions under which it may be grown, lumbered, and manu- 

 factured. This timber has suffered severely on account of the poor reputation given 

 to its eastern relative. The wood of the Western hendock is far superior to that of 

 the eastern tree and is suitable for all uses in ordinary l)uilding, for paper pulp, for 

 wooden ware, and particularly adapted to indoor finishing. The bark, which is 

 abundantly produced, contains half as much again of tannin as that of the eastern 

 tree. Under favorable conditions it reproduces abundantly and grows very rapidly. 



The Western hemlock is found from Alaska to California, and in the northern 

 portion of its range as far east as Montana. It seldom occurs as pure forest, but is 

 usually associated as a mixture with red fir, spruce, cedar, and in northern California 

 with redwood. The conditions favorable for the reproduction of hemlock are not 

 those which are advantageous for most of the associated species, and it is probable 

 that hemlock will reforest cut-over lands when red fir would fail to establish itself. 

 This tree frecjuently attains a diameter of 8 ft. and a height of 250 ft., although as a 

 rule the mature trees are from 3 to 5 ft. in diameter. It is very tolerant of dense 

 shade and germinates and grows readily under conditions which its associated species 

 would not tolerate. 



The principal enemies, both fungus and insect, are described, after which the value 

 of the wood for various uses, its durability, defects, etc., are shown. Tables are given 

 showing the value and yield of first and second growth hemlock in a number of 

 localities, and a l)rief statement given relative to the value of the bark as a source of 

 tanning material. A list of the trees of Oregon and Washington, which are asso- 

 ciated with the Western hemlock, completes the bulletin. 



The hardy catalpa in commercial plantations, W. L. Hall ( 11. S. Dept. Ayr., 

 Bureau of Forestry Bid. .i7, pp. 1-48, pis. ,?5).— Attention is called to the value of the
