but six feet instead of nine feet away from its base. The 

 leaf was on the same side as before, as was also the 

 flower. Sngar syrup, which is odorless, was placed on 

 each. At 1 :30 the bees finished the syrup on the feeder. 

 One bee flew almost immediately to the flower, but made 

 a brief stay. At 1 :34 a second bee came and sucked, and 

 three minutes later a third bee came. No bees had found 

 the leaf. 



Sugar syrup was again put on the feeder, and the 

 flower and leaf were moved three feet nearer its base, 

 each now being distant three feet. At 1 :47 the syrup on 

 the feeder was all consumed, but even previously one bee 

 had come to the flower. At 1 :47 a bee flew over the leaf, 

 but did not alight. At 1 :50 three bees came to the flower, 

 and a moment later a fourth, and afterwards two more. 

 At 2 p.m., there were three bees on the flower, a fourth 

 came a little later and then a fifth. No bees had visited 

 the leaf. 



Syrup of sugar was again placed on the feeder. At 2 :5 

 p.m., I put out the yellow flower and apple leaf used in 

 the first experiment. On these, it will be remembered, 

 honey had been placed. They were laid on the grass on 

 opposite sides of the feeder, each three feet distant from 

 its base. At 2:10 the sugar syrup on the feeder was all 

 removed. A bee soon came to the flower, but did not 

 stop, a second bee came and sucked, a third bee came, but 

 did not stop, several bees came but did not stop ; but at 

 2 :13 there were three bees sucking honey on the flower. 

 A bee flew slowly over the leaf I thought it would cer- 

 tainly be attracted by the scent of the honey, but this was 

 not the case. The experiment was continued a little 

 longer and one or two more visits were made to the 

 flower, but none to the leaf. 



The results obtained in the four preceding experiments 

 are deserving of careful attention. While the yellow 

 flower containing honey and the one containing scentless 

 sugar syrup were visited many times by bees, the leaves 

 remained wholly unvisited, though the supply of syrup
