. The testing of forest seeds during 25 years, 1887-1912 . respectively. The UMBRELLA PINE — SCIADOPITYS VERTICILLATA yieldsseed which germinates very slowly, in consequence of which itoften fails in the nursery; it must be sow^n very early in a warmbed ox-Jn-lhe ^eenhouse, or be prepared in^ winter in a warmjglace and then sow^n very early in the spring. As a rule the seed is good and retains its germinating capacityfor a long time. In 1909—10 the germination test proceeded as fol-lows: 17%, 76o/o and 88 /o, in 40, 60 and 100 days respectively. The handsome THUJOPSIS DOLOBRATA has continually yiel-ded only empty seed. Again and again I have received apparentlyfine seed from various parts of Japan, alw^ays how^ever w^ith thesame negative result. The seed is invariably empty. In 1905—06 itgerminated 1 per cent, the best result I have had. This species is, therefore, now^ struck out of my price lists. For the future the onlyconsolation that remains for us is that this fine tree can be fairlyeasily propagated by means of cuttings or layers.. THE SEEDSOF BROAD-LEAVED TREES EUROPEAN, NORTH AFRICAN AND WEST ASIATIC SPECIES It must be admitted at once that the results obtained from thetesting of the seeds of broad-leaved trees are only small compa-red w^ith those obtained by the testing of conifers. At the very beginning, 25 years ago, numerous experimentswere made, as shown by the tw^o first Reports, covering the businessyears 1887—88 and 1888—89. It soon became evident, how^ever, aswas generally expected — that these germination tests were forthe most part either unsatisfactory or produced no result whatever. ALNUS and BETULA. As far as the European species are con-cerned, the Alders and Birches form, indeed, a happy and valuableexception. The germination tests show very quickly and conclu-sively the real value of these seeds and in this way explain thegreat uncertainty in their treatment in the nurseries.
