Field experiments have been made, and are being continued under

scientific control, in a number of counties.; and maps have been made out showing the steady expansion of districts. where lucerne will now grow, though it would not in the past, solely because the little plant-animal of the soil was not present in the soil or not in sufficient force. The efficacy of treating the seed with this culture is now proved, and the discovery is a real addition to the wealth of the country. We have harnessed a beneficent animal to propel the wagon of productive pro- sperity. It seems probable that when this agent of fertility has been introduced and encouraged by the growing of the crop, the district will become permanently fit for lucerne without further adventitious aid.
