We see from this that the sections of the United States most favora- 

 ble to beet-root culture are confined to the north, including Xew Eng- 

 land, Xew York, a narrow band south of the lakes, Michigan, parts of 

 Wisconsin, Minnesota, and Dakota. Here the line of the southern 

 limit passes into the British possessions and enters the United States 

 again in Washington Territory, and, crossing Western Oregon, passes 

 to the coast to the extreme north of California. In most of this band 

 we find a favorable temperature, and the aveiage rainfall is sufficient in 

 quantity, but we are unable to make any observations concerning the 

 number of rainy days. In California, as the tables will show, the tem- 

 perature is sufficiently moderate, but, from examination of the figures 

 for the stations for which the rainfall has been recorded, we find it to 

 be remarkably deficient. Here, in order to make the culture a success, 

 it would appear that the intervention of irrigation during the summer 

 months would be an absolute necessity. 



We also note a few counties in the southwestern portion of Pennsyl- 

 vania, and one county in Ohio, without the general band, where suitable 

 meteorological conditions seem to exist. These counties are surrounded 

 by the red line in the more detailed map that has been prepared, show- 

 ing the county lines near to or over which the line of the limit of favor- 

 able meteorological conditions passes. This map is intended for more
