MARJORA.M. Origanum. "A ge- 

 nus of well - known, pungent, and 

 gratefully aromatic herbs. The plants 

 are all of easy cultivation ; the shrub- 

 by kinds are increased by cuttings or 

 slips ; the herbaceous species by di- 

 viding at the roots. There are as 

 many as eight species, besides nu- 

 merous varieties. The species gen- 

 erally cultivated are the common or 

 pot marjoram (O. vulgarc), and sweet 

 or summer marjoram (0. majorana), 

 and bastard or winter marjoram {0. 

 heracleoticum). 



" A light, dry, and moderately fer- 

 tile soil is required for their healthy 

 growth ; and if it is one that has not 

 been cropped for a considerable time, 

 it is the more favourable for them. 

 If the soil is wet or rich, they are de- 

 ficient in their essential qualities, and 

 the perennials are unable to with- 

 stand severe weather. The situation 

 cannot be too open. The sweet mar- 

 joram is propagated solely by seeds ; 

 the two perennials by seed, as well 

 as by parting their roots, offsets, and 

 slips of their branches. Sowing may 

 be performed of all the species, from 

 the conclusion of February, if open 

 weather, to the commencement of 

 June ; but the early part of April is 

 the usual time for performing it. Por- 

 tions of the rooted plants, slips, &;c., 



may be planted from February until 

 May, and during September and Oc- 

 tober. 



" The sowing is performed eithei 

 in drills, six inches apart, or broad- 

 cast, in either case the seed being bu- 

 ried not more than half an inch deep. 



" The tops and leaves of all the 

 species are gathered when green, in 

 summer and autumn, for use in soups, 

 &c. ; and a store of the branches is 

 cut and dried in July or August, just 

 before the flowers open, for winter's 

 supply." — (Johnson.) 



AIARK. The black dot on the cor- 

 ner teeth of the horse when five and 

 a half years old. It is gone, or rased, 

 when he is eight years. 



MARKETS, AGRICULTURAL. 

 "The more numerous markets are in 

 any well-cultivated country, provided 

 they are at a sufficient distance not 

 to interfere with each other, and on 

 different days of the week, the great- 

 er saving there is of time and labour 

 of conveyance. Good roads or nav- 

 igable rivers are of great importance 

 to a market-town ; and if there are 

 mills in the neighbourhood where 

 corn can be ground, they will increase 

 the advantage to the farmer by caus- 

 ing a regular demand above what the 

 immediate consumption of the place 

 may require. 



" The vicinity of a good market, 

 where every kind of agricultural prod- 

 uce will always find purchasers at a 

 fair price, greatly adds to the value 

 of a farm, especially if good roads 

 lead to it ; and the advantage is the 

 greater if it be a populous town, which 

 not only consumes much produce, but 

 from w hich various kinds of manure 

 may be brought by the teams which 

 have carried the produce to market. 

 It is this which so much enhances 

 the rent of land near London and all 

 great cities, and makes the agricul- 

 ture there approach nearer to horti- 

 culture, which entirely depends on 

 extraneous manure " 



MARKING INK. See Indelible Ink. 



MARKING NUT. The seed of 

 the Semicarpus anacardiiim, a tropical 

 tree, the juice of which stains linen 

 of an indelible black.
