beds should be given a dressing of manure to encourage the coming winter 

 crop, and new rhubarb plantations may now be established. 



Flower Garden. 



The hot dry weather has made havoc in some flower gardens, and, as a 

 result of this weather, red spider has been prevalent on some succulent and 

 herbaceous plants. 'I'hese should be destroyed, particularly where dahlias 

 are growing ; or a good nicotine spraying should be given if the plants are 

 to be retained. 



Chrysanthemums, roses, and dahlias will now all be coming into bloom ; 

 and as these show their bloom buds, they should be fed with liquid 

 manure weekly. 



All classes of spring flowering bulbs, as well as hardy annual, biennial, 

 and perennial seeds, should be planted and sown. 



Roses should be watched for mildew attacks, and the sulphur should be 

 freely used for this. Plantings of shrubs and trees may now be made, 

 and wherever flowering shrubs have ceased to bloom, thev may be pruned. 

 Frequent cultivation and watering will be necessary, especially if the 

 weather continues hot and drv.

II.— ITS STRUCTURE AND NUTRITION. 



One of the most interesting chapters in the h'story of agricultural 

 science is that relating to the discovery of the food requirements of plants. 

 More than a century of careful scientific investigation was necessary to 

 establish the f'lndnrrental facts of plant nutrition and on this basic know-

 of the present article is to supply a simple account of the more important 

 of the facts of plant nutrition by using our staple farm crop as an illus- 

 tration.
