THE GROWTH OF THE SHOOT FROM THE BUD 59 



observe hedges, noting the difference in annuals and biennials ; 

 or they can climb some hill and compare the stunted growth of the 

 herbs at the top of the hill with the more luxuriant vegetation of 

 the valley below. In winter they can note the manner in which 

 the buds are protected, and in the spring the folding of leaves 

 in the bud. 



Students that live in towns may do much with a small garden. 

 Climbing plants may be observed in the Nasturtium, Scarlet 

 Runner, or Kidney Bean ; buds in such shrubs as the Lilac or the 

 Laburnum ; the stem of the biennial Wallflower may be compared 

 with that of a perennial Sunflower. Simple experiments, such 

 as those indicated, may be tried by any one who has the necessary 

 patience, and experiments help in the interpretation of Nature. 

 In teaching, the important thing is to plan the experiments 

 so that they succeed each other in a right order, the one following 

 naturally on the other. The best time of year for experiments 

 on the life and growth of plants is undoubtedly the spring, because 

 the vital activity of the plant is then specially great ; but even 

 in the autumn and winter a great deal can be done, provided 

 care be taken to secure a right temperature.
