established plants the Wichuraiana 

 and hardy climbing roses should be 

 pruned just after blooming. At this 

 time young shoots will have started 

 from the roots. The growth of these 

 shoots should be encouraged, as it is 

 from them that most of the branches 

 are produced that bear the following 

 year's bloom. The best way is to re- 

 move all the old wood at this time, so 

 that all the strength will go into the 

 young shoots. Where the roses are 

 trained over a trellis so high that one 

 season's growth will not cover it, the 

 method just described is not practi- 

 cable. In such cases some of the old 

 shoots should be cut off at the ground. 

 and the others should be shortened 

 from 3 to 6 feet, depending on the 

 amount of growth the vine has been 

 making each year. New shoots should 

 be trained to take the place of those 

 removed. It should be kept constant- 

 ly in mind that the present year's 

 growth bears next year's flowering 

 branches aud that a few vigorous 

 branches are more desirable than 

 many weak ones. 



REMEDIES FOR GRASS DISEASES. 

 First and foremost the best treat- 

 ment in all cases where grass is at- 

 tacked by disease is to mow the turf 

 as closely as possible and then to en- 

 courage a strong growth of grass by 

 quick-acting manures, so as to enable 

 the grass to grow away from the 

 disease. In soft shady turf, and on 

 those golf courses that lie on river 

 flats where fungoid diseases spread 

 very quickly, drastic treatment may 

 be rendered necessary. In this case, 

 spraying with sulphide of potassium 

 (one ounce to ten gallons of water) 

 may be done. Permanganate of potash 

 diluted to a clear rose color also makes 

 a useful preventive, and applications 

 of flowers of sulphur applied when the 

 grass is wet may be recommended for 

 bad outbreaks of the red mould, etc. 

 Excei)ting in cases where soil is sour, 

 solutions of Kainit (one ounce per 

 gallon) are useful in helping the grass 

 to resist mild attacks of rust, etc. 

 Dry lime is particularly useful in most 

 cases, excepting that it is always well 

 to avoid using lime as much as pos- 

 sible, as it encourages clover. 



All dressings are best applied in the 

 evening, as it is during the night that 

 mildew spreads most rapidly. On soils 

 liable to repeated attacks of various 

 grass mildews, the excessive use of 

 nitrogenous and crude acid manures 

 should be avoided, and where it is 

 necessary to hasten the growth with- 

 out unduly forcing the grass, phos- 

 phatic dressings should be used. Hone • 

 meal must be blamed for causing a 

 large amount of fvmgoid growth as well 

 as encouraging clover: whilst leaf 

 mould, especially that from ash and 

 sycamore leaves, also sets up mil- 

 dews, though the advantages of the 

 leaf mould may possibly outweigh the 

 disadvantages. 



Most of the diseases are noticeable 

 when they are in the form of white, 

 gray or orange-colored moulds, this 

 generally being the spore-bearini; 

 stage. It is then that precautions to 

 prevent the disease from spreading 

 should be taken. Rough grasses in 

 hedgerows, reeds and rushes are 

 nearly always infected with rust and

other diseases, so these should be 

 kept cut down as much as possible. 

 Cigarette ends and bits of rag lying in 

 the turf are frequently the starting 

 place of the white grass mildew. 

 Leaving cut rye grass on the turf is 

 also particularly bad, as a poisonous 

 ferment is set up by the rye grass 

 leaves that rots the finer grasses. 



There is, however, a brighter side to 

 this gloomy lecture, for parasitic fungi 

 are not always injurious to the plants 

 on which tbey live, aud in some cases 

 plants when infested with a particular 

 para side often grow more robust and 

 vigorous than the non-infested plants. 

 This condition, known as symhio.iis. is 

 noticeable in the case of rye grass. 

 Kven if grasses have their parasitic 

 enemies, all plants are affected in the 

 same manner, and, like "the fleas that 

 have lesser fleas upon their backs to 

 bite 'em, " so these different mildews 

 and fungi have other moulds that live 

 upon them, which keeps the balance of 

 Nature and prevents every blade of 

 grass in the country from being de- 

 "stroyed. The Yrlloic Rattle is also 

 punished for its greedy disposition of 

 living on the grass roots by suffering 

 in its turn from a parasitic fungus thai 

 causes gouty swellings on its roots.

A NEW USE FOR DAHLIAS 



There is a chemical substance 

 called 'Inuline." This substance is 

 necessary for the production of the 

 serum used in anti-typhoid and anti- 

 typhus inoculations. Hefore the war 

 Germany sui)plied this. Since then 

 chemists have discovered that this 

 can be extracted from the root of the 

 dahlia, and as only two per cent, is 

 yielded from the root, great quantities 

 of the root must be obtained to fulfil 

 the demands of the government. —
