GRAPE DISEASES 



Downy Mildew, Blackrot, Anthracnose. 

 Spray the canes with copper sulphate i lb. to 50 gallons before growth 

 begins. Follow this solution with diluted Bordeaux mixture (omitting Paris 

 green) or ammoniacal copper carbonate immediately after the fruit sets. Repeat 

 at intervals of three weeks, till the bunches begin to color. Ammoniacal copper 

 carbonate should always be used for the later applications. 



PLUM AND PEACH KOI' — {Manilla.) 



Without being fully tested the following course of treatment is recommended 

 for trial. Spray as soon as the fruit sets with sulphate of copper 3 ozs. to 45 

 gallons; follow this with diluted Bordeaux mixture to which Paris green has 

 been added, for the purpose of checking attacks of the curculio. If rot develops 

 late in the season, as is sometimes the case just before the ripening of the fruit, 

 spray again with sulphate of copper solution, or ammoniacal copper carbonate. 



COOSHl'.EkRY MILDEW. 



This disease can be effectually treated by using either ammoniacal copper 

 carbonate or Bordeaux mixture (No. 1), but as potassium sulphide (liver of 

 sulphur) serves the same purpose, is somewhat cheaper and more easily pre- 

 pared, it is therefore recommended here. 



Treatment should commence with the first signs of growth and continue at 

 intervals of ten or twelve days till five or six applications are made.

THE NIGHT-BLOOMING CEREUS. 



Like one enchanted, waiting in dark tower 



The " fated fairy prince'' to break the spell, 



A sheath-hid bud all day did darkly dwell. 



No morning breeze had kissed it into flower, 



Nor had it freedom found through sun or shower : 



World-hidden as a nun in cloistered cell. 



Vainly the bold bee strove its sweets to tell, 



A star in daylight veiled, it bode its hour. 



At evening's dusk a mist-pearled moonbeam came ; 



By love-light wakened, swift the flower soul thrilled. 



Slipt its dream robe, shone forth in life fulfilled ! 



Folding snow petals back from heart of flame, 



In sweet amaze it perfumed all the air, 



To find itself so blest, the world so fair.
