Page 324 - All that is necessary to hasten this, if desired, is to assist the seed coat in splitting. This is best effected by holding the seed firmly, and rasping off with a file both edges at the radicular end. It is best not to file off the actual end, as it may thus easily happen that the radicle of the embryo may be injured. After this treatment, properly performed, the young plant appears above ground in two or three weeks. The seedlings require no particular attention. They grow rapidly and may be finally...
Page 325 - The milk then exudes and runs down iu many tortuous courses, some of it ultimately falling on the ground. After several days the juice becomes dry and solid, and is then pulled off in strings and rolled up in balls or put into bags in loose masses. Only a thin paring should be taken off, just deep enough to reach the milk vessels ; but this is not always attended to. Nearly every tree has been cut through the bark, and a slice taken off the wood. Decay then proceeds rapidly, aud many of the trunks...
Page 64 - The objects of the club, as set forth in the proposed rules, are as follows : — " The investigation of the natural history, geology, and archaeology of the County of Essex (special attention being given to the fauna, flora, geology, and antiquities of Epping Forest), the publication of the results of such investigations, the formation of a library of works of local interest and other publications, and the dissemination amongst its members of information on natural science and antiquities.
Page 324 - The seed-coat is of remarkable thickness and very hard, and the natural process of germination occupies a long period — it is said more than a year. All that is necessary to hasten this, if desired, is to assist the seed-coat in splitting. This is best effected by holding the seed firmly, and rasping off with a file both edges at the radicular end...
Page 324 - These should be taken from the points of strong shoots, and may he one foot in length. In planting, each cutting may be put down in the soil to a depth of six inches. If scarce, the entire shoot may be cut into pieces, each possessing a bud, all of which will grow if covered with half-an-inch or so of soil. On loose sandy soils or exhausted coffee land, plantations may be formed at little expense. Hard dry gravelly wastes, if found to support any kind of bush, are also suitable sites.
Page 323 - ... from the fierce rays of the sun. The soil was in places a sort of soft sandstone or gravel which was bound up in the most extraordinary manner. Neither grass nor weeds grew among this underwood, and there was an entire absence of ferns, mosses, and other plants.' In another place somewhat further from the coast, the traveller, shortly after entering the bush-like forest, 'came on a large tract of land covered by immense masses of grey granite, some of which might be fifty tons or more in weight....
Page 324 - I would suggest the formation of plantations by cuttings, which will take root as easily as a willow. These should be taken from the points of strong shoots, and may be one foot in length. In planting, each cutting may be put down in the soil to a depth of six inches. If scarce, the entire shoot may be cut into pieces, each possessing a bud, all of which will grow if covered with half-an-inch or so of soil.
Page 323 - Mandiocca and other crops require to be irrigated. The rainy season is said to begin in November and end in May or June ; torrents of rain are then reported to fall for several days in succession, after which the weather moderates for a brief space. According to some statements there are occasional years in which hardly any rain falls. This assertion concurs with the aspect presented by the country in general. The daily temperature on board the ship ranged from 82° to 85" P., but inland it is often...
Page 323 - At Pacatuba, about forty miles from Ceara, the actual place where the specimens were obtained, ' the general forest was tolerably high, but the sparse small foliage did not afford much shade from the fierce rays of the sun. The soil was in places a sort of soft sandstone or gravel, which was bound up in the most extraordinary manner. Neither grass nor weeds grew among this underwood, and there was an entire absence of ferns, mosses, find other plants.
Page 347 - In the basidiomycetes, ascomycetes, and some other classes, it is proposed to substitute the term fructification for ' receptacle,' for the entire non-sexual generation which bears the spores. A list is appended of the terms in more frequent use which are disused in the proposed system.
