REMEDIES FOR FUNGOID DISEASES OF WHEAT. 115 



suggested by Professor Henslow, and, on the mode of fur- 

 ther conducting them, we beg to suggest the following. 

 The seeds thus obtained should then be finally packed, and 

 with each packet a note given of the process under which 

 it has been placed ; or simply marked with the number of 

 the experiment, as " No. 9," which will indicate that it 

 has been washed with stale urine. Different plots of 

 ground should then be laid out, one plot allotted to the 

 seeds of one packet. A slight sketch-map being taken of 

 the whole as arranged. 



It will be necessary to have the plots separated a con- 

 siderable distance from each other, at least three feet. 

 And comparative observation as to the conduct so to 

 speak of the contents of each plot will be more easily 

 made if the seeds are dibbled at distances of 9 or 12 inches 

 each way. A register should be kept of each plot, the 

 produce of each, the time when the disease if any ap- 

 pears, and the number of diseased grains obtained from 

 each. The produce at harvesting of each plot should be 

 carefully kept separate in packets and labelled for further 

 experiments or examination. All this will be troublesome 

 doubtless; but having conducted a large number of experi- 

 ments bearing upon different points in this careful way, 

 we can, from our own experience, promise those who may 

 conduct similar ones to those we have indicated, a large 

 amount of positive pleasure in carrying them out. It is 

 difficult, indeed, to give one any idea of the interest which
