PLANTING APPLE TREES. 



49T. Sir, —Please tell me if 20 x 20 feet would be far enough apart to plant apple 

 trees in a small orchard, in this locality, where cold winds prevail in winter. 



W. C. C, Ottawa. 



Unless for very small growing varieties the distance named is too small. Dwarf 

 apples would do well at this distance, but for most of the vigorous growing 

 standards, thirty-five feet each way is none too much. We have some old trees 

 at Grimsby whose branches are interlocking at a distance of forty feet each way. 



PRUNING THE BLACK WALNUT. 



49S» Sir, — When is the best season to prune black walnut trees, three or four years 

 old? 



0. T. B. , Kinijs Court. 



The best time for pruning all deciduous trees for the encouragement of 

 wood growth is between the fall of the leaf and the beginning of the growth in 

 the spring. Pruning during the summer season is a check to the wood growth. 



NEW BLACK CURRANT. 



49!>. 81R. — I send you saniple of new seedling black currant. Do you think it worth 

 propagation ? Tuos, Conolly, Lindsay. 



Could not answer without watching habit of plant. Better send a plant to 

 Experimental Farm, Ottawa, for testing. The quality is very ordinary, and 

 taste bitter. 



Containing questions for our readers to answer. 



7. Can you suggest points, rules and regulations to be observed by tiie jurors in 

 judging fruits at Chicago? The ordinary methods of ju<lginj^ will not be suHicieut where 

 the fruit of all climates ai)pear, and especially where so much will be in competition of the 

 same variety, grown umler so many varying circumstances, dilfcring climates, etc. Have 

 you particulars for a scale of points for judging, and what point would you advise to 

 observe specially, and how would you divide the points in tlic scale ? 



8. Is the Hangor Blackberry of any value where Snyder will not succeed ? 



9. Is the one judge system at fairs an advantage of throe judges ? 



10. What package is best for shipping onions ?
