The above list of introductions would indicate that the efforts of 

 the Department of Agriculture were not confined to obtaining seed 

 from a particular locality or region. Nevertheless, since the project 

 was inaugurated mainly to aid in the solution of the hardy and 

 drought-resistant alfalfa problems, special attention was focused 

 on parts of Eussia and Siberia having climatic conditions compara- 

 ble with the colder and drier portions of the North and Northwest. 

 Although many plants, especially perennials, are found growing 

 under a wide range of climatic conditions, it is nevertheless of in- 

 terest in the case of the introduction of Medicago falcata to compare 

 certain features of the climate of points in Eussia and Siberia, where 

 the species is found growing naturally in some abundance, with 

 points in the northern and northwestern parts of the United States. 

 Table I indicates the seasonal and normal ajinual precipitation and 

 the maximum, minimum, and mean annual temperatures for points 

 in Eussia and Siberia and in certain Northwestern States.
