the soil, and within a day or two many plants showed injury, 

 especially those which came accidentally in contact with the mix- 

 ture. Several plants died from this poisoning, several recovered, 

 and all probably received more or less injury. The plants that 

 succumbed to the trouble w&re discarded from the experiment. 

 The injured plants recovered after two or three weeks, and since 

 the check to growth was probably equally distributed amongst all 

 the lots, the results are comparable. This assumption is supported 

 b}'' weights obtained (see Table IV). 



The plants set in the field numbered: Of the cross, Dwarf 

 Aristocrat x Livingston Stone, 36 of first generation, 80 of 

 second, 73 of third, and 65 of fourth ; of Livingston Stone, 80 ; 

 and of Dwarf Aristocrat, 44. The number from which data 

 were secured is given in the following table.
