WONDEES OF A STAGNANT POOL. 



Aftee long confinement to the house, whether 

 from illness or an unusual pressure of en- 

 gagements, how delightful to turn out for a 

 stroll in the fresh pure air ! Unheededwhether 

 it rain or shine, if a naturalist of the true 

 stamp, all around seems to welcome him, and 

 care aiid trouble for the time fly far away. 

 It was early in the morning, recently, that, 

 in urgent need of a breath of fresh air, we 

 started for a walk before breakfast ; rain had 

 fallen heavily during the night, and the air 

 was still reeking with moisture. One trouble, 

 and one alone, was ours during the walk — 

 "What shall we contribute to our readers in 

 the next Eeceeative Science ? One subject 

 we had given much time to presented so 

 many new features requiring careful and 

 prolonged examination, that it had to be left 

 for further time and opportunities ; so on in 

 meditative mood we walked, till our thoughts 



turned to the teeming abundance of the lower 

 classes of vegetable life, and the important 

 part they play in the grand scheme of life 

 on our globe. 



Coming, then, to a stagnant, foetid ditch, 

 our attention was caught by the unusual 

 quantity of a blackish-green slimy-looking 

 substance, at the bottom, sides, and floating 

 on the top by means of entangled air. Some 

 of this was gathered. A similar material by 

 the side of the road, left by a now dried-up 

 rain-pool, furnished another gathering, each, 

 for lack of a better means of conveyance, 

 being placed in a bit of paper, and trans- 

 ferred to the waistcoat-pocket. A little 

 further on the palings, the trees, the very 

 walls in parts, were covered with a bright 

 green powdery -looking substance, as if they 

 might have been recently painted, some of 

 which was carefully scraped off"; and, lastly.
