The Canadian Horticulturist. 



now attributed many of the deadly 

 diseases which affect man and 

 animals. In this we believe no 

 one has as yet contradicted him, and 

 indeed, when it is so hard to study 

 the habits of the visible creation, few 

 of us will attempt to disprove the 

 statements of the careful scientist 

 with regard to microscopic life. The 

 germ of the pear blight is described 

 as egg-shaped and consisting of a 

 single cell which multiplies by divi- 

 sion across its middle. It has no 

 mouth, stomach, leaves or roots and 

 can only take in nourishment by ab- 

 sorbtion. The only way in which it 

 can gain entrance to the cells of the 

 pear tree is through wounds or 

 through such young and tender parts 

 as are not yet protected by a skin- 

 like covering, e.g., through the tips 

 of growing twigs. Once there, it 

 absorbs for its own development the 

 materials stored up in the cells for the 

 tree, and increases with such rapidity 

 that there are soon millions of them 

 in a single twig. 



The only remedy proposed is care- 

 ful cutting away of the affected parts. 

 The extent of the injury can usually 

 be seen by close examination and 

 when the lowest limit is found, the 

 whole of the part should be cut away, 

 and the wound painted with raw 

 linseed oil and lead to exclude re- 

 entrance. 



Comparative Apple Shipments. 



The following table of apple ex- 

 ports from years 1880 to i88g, may 

 be interesting to Canadian apple 

 growers. From this we learn that 

 last year was the heaviest exporta- 

 tion ever made of apples from the 

 American continent ; and if we could 

 read behind the scenes, no doubt we 

 would also learn that it was on the 

 whole the most disastrous to ship- 

 pers. We notice that New York 

 is the largest port of export, and 

 Montreal and Portland next. We 

 class them together, because Port- 

 land only takes the place of Montreal 

 when that is closed by the winter. 



The table is prepared by R. Dixon, 

 of New York City.
