INTRODUCTION 
Gardening is one of the healthiest and most invigorat- 
ing of all hobbies or occupations. 
Further, one cannot cultivate the soil, sow seeds, tend 
seed beds, or watch the growth of plants without becom- 
ing conscious of a great unseen power, a power undefin- 
able, yet manifestly present to all who take up this occupa- 
tion. When we look more minutely into the construction 
of plants, examine the different parts under a microscope, 
study the work allotted to each, and the relations between 
the parts, we cannot but wonder at the perfect adjust- 
ment of each and every part, all so intricate, and yet so 
perfect. How could such perfection be brought about? 
we ask. As we begin to think, our minds become broader, 
and the more we study our plants the more interested 
we become in trying to unravel the sublime secrets of 
Nature. The cares and trials of life, which seem, at 
present, to sap our whole strength, and leave us listless, 
gradually fade away before this all-absorbing study. 
Let every young gardener make up his mind to leave 
his profession better than he found it, and work with that 
aim in view. He will have discouragements and take

progress is sure to be made. He may not reach his final
