THE CANADIAN HORTICULTURIST.

These lawns are just as green in the 

 middle of summer as in the early 

 spring. They have been during that 

 time, six years, mowed once a week all 

 summer, and when vegetation is rapid 

 twice. Never, if possible, allow your 

 grass to get so long as to requii-e raking 

 oif ; cut as short as it will drop unseen, 

 as it will do much to mulch and retain 

 moisture. 



In winter beware of allowing roads 

 to be formed by foot'passers, or other- 

 wise, for if you do, your grass is sure 

 to be killed by the formation of ice, or 

 leave an unsightly track for a portion 

 of the summer. If ice has formed on 

 any part of it, cover it up with snow or 

 something else, for as sure as the 

 sun strikes through this ice so sure 

 will your grass be scalded out. Dry 

 frosts early kills grass unless there is 

 an over-abundance of moisture. I 

 generally have snow taken from about 

 doors and put on to such places.

A SURE PREVENTIVE OF CHICKEN 

 CHOLERA. 



Several experiments have been made 

 during the last five years by different 

 parties for the purpose of preventing 

 the spread of chicken cholera, by in- 

 oculation or vaccination. We have 

 during the pa^t two years vaccinated 

 the fowls in nineteen different yards 

 where the cholera was prevailing badly, 

 and in each yard we left some common 

 fowls not vaccinated, and they all died. 

 Out of the 2,000 vaccinated only eleven 

 died, although they were in the same 

 yard with those not vaccinated that were 

 dying daily by the scores. We have 

 every reason to believe that this chicken 

 vaccination is as effective in preventing 

 cholera among fowls as vaccination is 



in preventing smallpox among the 

 human family. Vaccinate a hen and 

 in eight days its system will be thor- 

 oughly inoculated, then cut off her 

 head, and catch all the blood in some 

 vessel, then pour the blood out on 

 paper to dry ; a half drop of this blood 

 is sufficient to vaccinate a hen, and the 

 blood of one hen will vaccinate a whole 

 flock. Catch the fowl you wish to 

 vaccinate, and with a pin or knife 

 make a little scratch on the thigh (just 

 enough to draw blood), then moisten a 

 little piece of the paper with the dried 

 blood on and stick it on the chicken's 

 leg where you scratched it, then let the 

 fowl run, and yon need have no fear 

 of chicken cholera. As the result of 

 many experiments, I have now dried 

 blood enough, I suppose, to vaccinate 

 ten thousand fowls, for which I have 

 no use, as I do not sell patent medicines. 

 If any of your readers are enough inter- 

 ested in poultry to try this preventive, 

 by writing to me I wdll send you free 

 of any charge enough dried blood to 

 start with. All I ask is that they send 

 immediately, before the blood loses its 

 strength, and re})ort the result of their 

 experiment to your many readers.

PRIMO STRAWBERRY. 



This has not been a favorable season 

 for the strawberry, so cold and back- 

 ward that the general crop is consid- 

 ered light. I have experimented with 

 all the now leading varieties for the 

 last ten years, and have grown straw- 

 berries for the New York market, and 

 I have not found a strawberry to fill 

 the bill so well as the Primo. This is 

 the second year that I have fruited it.
