It may be thought that before concluding this paper 

 I should say something about the humbler denizens of 

 the garden the bulbs and flowering plants which add so 

 much to the beauty of our parks and recreation grounds. 

 But this opens up a wide field, which can hardly be satis- 

 factorily traversed within the limits of space at my dis- 

 posal. I can only say that many bulbs and herbaceous 

 plants are available here. By bulbs I do not mean merely

 accustomed, but to many things, as Scillas, Narcissus, Iris, 

 Gladioli, Crocuses, and Snowdrops, which would do well 

 if planted in rich sandy soil. 



One strong reason for the use of bulbs is, that they 

 can be brought to their work in a prepared and efficient 

 state, and can be renewed yearly where necessary. Per- 

 haps there are but few instances in which they would 

 prove satisfactory if allowed to remain to flower a second 

 year, when the previous year's growth had been made 

 under the trying influences of a town atmosphere. The 

 same may be said of some bedding and herbaceous 

 plants they should be renewed annually.

 polyandria. In the botanical catalogues it is described as 

 a hardy biennial with red flowers, blooming in August
