:i. Meriana, Mill. This seems to be the dominant 

 species of the genus and henee the most variable and 

 the one most interesting to the plant-breeder. In its 

 widest sense it includes W. iridifoUa, but for horti- 

 cultural purposes it will be convenient to consider the 

 latter a distinct species. W. Jfrr'-ni-i i-^ hr-^t rrsrricted 



to the commonest type at the i ': . i > i. , i, ,^,.-ti,i.

 plant figured in B.M. 418 as .Ic.'. ';,. / 1/ . ../.-(. (in. 

 17:230 is more typical in color. The white-ttd. form, 

 which is rarer in nature, is treated under W. iridifoUa. 

 Baker says that there are scarlet-fid. forms of this spe- 

 cies, but he gives them no name, and it is probable that 

 all such should be referred to W. angusta. 



4. iridifdUa, Ker. This is treated by Baker as a va- 

 riety of W. Meriana characterized by broader Ivs. than 

 the type: fls. closer and more numerous, white or pink- 

 ish. For horticultural purposes it will be convenient to 

 treat it as a distinct species and restrict the name to 

 the pink or rose-colored type.

5. densifWra, Baker. This very distinct and hand- 

 some rose-colored species more nearly resembles a 

 gladiolus than any other by reason of the density and reg- 

 ularity of its pyramidal inflorescence. Stems unbranched, 

 2-3 ft. high: spikes a foot long: fls. bright rosy red. 

 B.M. filOO. -There is a choice variety with pure white 

 fls. Var. 41ba, Hort., was introduced as early as 1891. 



6. cocclnea, Herb. This showy scarlet-fld. species 

 differs from IF. Meriana in Its stem being shorter and 

 unbranched, the spikes fewer-fld. and the styles a trifle 

 longer. Stem 1 ft. high: spikes 4-6-fld. B.M. 1194 ( IT. 

 Meriana variety). 



7. htimilis, Mill. This species has rose-red fls. ap- 

 parently the same size and color as W. densitlora but 

 only 4-G in a spike and the stem only a foot or so high. 

 B.M. 631. -A variegated form figured in B.M. 1193 as 

 W. roseo-alba has a spike of 8 flesh-colored fls. with 

 broad bands and splashes of scarlet. 



8. rdsea, Ker. Robust rose-colored species, growing 

 4-6 ft. high and the fls., though fewer than those of IT. 

 densiflora, are perhaps capable of greater size. Spikes 

 about 15-fld. B.M. 1072. 



W. nrgilta, Hort. .John Saul. 189S, is presumably a c.italogue 

 error, as uo such name appears in Baker's latest monograph.

WEEDS. It would have been a sorry thing for agri- 

 culture if there had been no weeds. They have made 

 us stir the soil, and stirring the soil is the foundation 

 of good farming. Even after we have learned that 

 crops are benefited by the stirring of the land, we are 

 likely to forget the lesson or to be neglectful of it un- 

 less the weeds constantly remind us of it. Necessity is 

 always the best schoolmaster; and of these necessities, 

 weeds are amongst the chief. 



A weed is a plant that is not wanted. There are, 

 therefore, no species of weeds, for a plant that is a 

 weed in one place may not be in another. There are, 

 of course, species that are habitual weeds; but in their 

 wild state, where they do not intrude on cultivated 

 areas, they can scarcely be called weeds. The common 

 pigweed and the purslane are sometimes vegetables, in 

 which case potato plants would be weeds if they grew 

 among them. 



The one way to destroy weeds is to practice good

farming. .Judicious tillage should always keep weeds 

 down in cultivated lands. In idle lands weeds are likely 

 to be a serious nuisance. In sod lands they are also 

 likely to take the place of grass when for any reason the 

 grass begins to fail. The remedy for weeds in grass 

 lands, therefore, is to secure more grass. In order to 

 • 1.. so, it may be necessary to plow the land and reseed. 

 Ill some cases, however, it is only necessary to give the 

 1:iih1 :i light surface tillage, to add clean and quickly 

 a\ailable fertilizers and to sow more grass seed. This 

 is the fundamental remedy for weeds on lawns. If such 

 weeds are perennial, as dandelion and plantain, it is 

 advisable to pull them out; but in order to keep them 

 out, a stiffer sod should be secured. The annual weeds 

 that come in the lawn the first year are usually de- 

 stroyed by frequent use of the lawn mower. 



Foul lands may usually be cleared of weeds by a 

 short and sharp system of rotation of crops, combined 

 with good tillage in some of the crops of the series. 

 When the land for any reason is fallow, — as when it is 

 waiting for a crop, — surface tillage with harrows or 

 cultivators will serve to keep down the weeds and to 

 make the land clean for the coming crop. Often lands 

 that are perfectly clean in spring and early summer 

 become foul in the fall after the crops are removed. 

 Cleaning the land late in the season, therefore, may be 

 one of the most efficient means of ridding the land of 

 weeds. Coarse and rough stable manure, which is not 

 well rotted, may also be a conveyer of weed seed. The 

 seeds of weeds are sometimes carried in the seed with 



It does not follow that weeds are always an evil, even 

 when they are abundant. In the fall a good covering of 

 weeds may serve as an eflicient cover-crop for the 

 orchard. They are likely to entail some nxtra care the 

 next year in order to "prevent tiuin Irom i.':Miiiiig a 

 mastery, but this extra care benelii- tlio ojiIkhiI at the

crop oneself, for then the orchar<list smins wliat he 

 wants and of the proper quantity and at the right sea- 

 son; but a winter cover of weeds is usually better than 

 bare earth. 



From the above remarks it will be seen that weeds 

 are scarcely to be regarded as fundamental difficulties 

 in farming, but rather as incidents. In the most inten- 

 sive and careful farming the weeds bother the least. 

 There should be a careful oversight of all waste areas, 

 as roadsides and vacant lots. Experience has shown 

 that the greatest difficulty arises on commons and waste 

 land, not on farms. 



Weeds are often troublesome in walks, particularly in 

 those ni.aili- of irr.-iv.-l. If the walk were excavated two
