The flowers are shipped to Penzance, and thence carried by rail in special carriages. At the top of the season thirty to forty tons are shipped in a single day. The total exports, which were only 100 tons in 1887, have now reached 1,000 in 1907. M.--IRRIGATED MEADOWS IN ITALY. In the _Journal de l’Agriculture_ (2nd Feb., 1889) the following was said about the _marcites_ of Milan:-- “On part of these meadows water runs constantly, on others it is left running for ten hours every week. The former give six crops every year; since February, eighty to 100 tons of grass, equivalent to twenty and twenty-five tons of dry hay, being obtained from the hectare (eight to ten tons per acre). Lower down, thirteen tons of dry hay per acre is the regular crop. Taking eighty acres placed in average conditions, they will yield fifty-six tons of green grass per hectare--that is, fourteen tons of dry hay, or the food of three milch cows to the hectare (two and a half acres). The rent of such meadows is from £8 to £9, 12s. per acre.” For Indian corn, the advantages of irrigation are equally apparent. On irrigated lands, crops of from seventy-eight to eighty-nine bushels per acre are obtained, as against from fifty-six to sixty-seven bushels on unirrigated lands, also in Italy, and twenty-eight to thirty-three bushels in France (Garola, _Les Céréales_). N.--PLANTED WHEAT. _The Rothamsted Challenge._ Sir A. Cotton delivered, in 1893, before the Balloon Society, a lecture on agriculture, in which lecture he warmly advocated deep cultivation and planting the seeds of wheat wide apart. He published it later on as a pamphlet (_Lecture on Agriculture_, 2nd edition, with Appendix. Dorking, 1893). He obtained, for the best of his sort of wheat, an average of “fifty-five ears per plant, with three oz. of grain of fair quality--perhaps sixty-three lbs. per bushel” (p. 10). This corresponded to ninety bushels per acre--that is, his result was very similar to those obtained at the Tomblaine and Capelle agricultural stations by Grandeau and F. Dessprèz, whose work seems not to have been known to Sir A. Cotton. True, Sir A. Cotton’s experiments were not conducted, or rather were not reported, in a thoroughly scientific way. But the more desirable it would have been, either to contradict or to confirm his statements by experiments carefully conducted at some experimental agricultural station. Unfortunately, so far as I know, no such experiments have yet been made, and the possibility of profitably increasing the wheat crop by the means indicated by Sir A. Cotton has still to be tested in a scientific spirit. O.--REPLANTED WHEAT. A few words on this method which now claims the attention of the experimental stations may perhaps not be useless.
