New Soil Series Established During 1937

I am submitting herewith a list of 435 new soil series names that have been established and reported to us during the past year. Of these, 184 are reported by the Bureau of Chemistry and Soils of the United States Department of Agriculture including 100 new series that have been established in Puerto Rico. The work in Puerto Rico has been underway for nearly five years, but the reporting of the series names has been delayed until the completion of that work and the correlation of all of the series and types established. These have been indicated in the list by the letters P. R. to follow the custom adopted in the Bibliography which was originally prepared in 1933 and which is now being published by the Bureau of Chemistry and Soils. Mexico has 'contributed a total of 163 names of new soil series. Again, these include not only work of the current, year but also some that had not been previously reported. New Zealand has reported fifty-six new series, part of these having been established prior to this last year but not previously reported. Australia has reported thirty-two new series. In this list of 435 new names there are eighteen duplications. Two names that appear for the first time have been used in surveys in different countries} sixteen names of the new series were used previously for soils of different character. Each is indicated in the list with the Initials of the country in which they have been found. In addition to the names included in this list, I have received the names of the following series that are provisionally established in soil surveys in Ontario: Brighton, Trenton, Dartford, Bondhead, Otonabee, Frontenac, Durham, Lovett, and Cramahe. They are not included In the list because they have not as yet been definitely correlated and finally approved. Two of these, the Trenton and Durham, are already in use for soils of the;United States that are different from those so named in Canada; the Trenton series being recognized in Utah in 1913 and the Durham in North Carolina in 1900. In addition to the names that have been reported, we know that surveys have been carried on in both North and South China but due to the stress of present circumstances the names have not been reported. Additional survey work is also progressing in other parts of the world, and it.is hoped that the names of the series established in these surveys may be Included in the lists that can be submitted next year. We have already thanked personally each of the contributing organizations and wish again to express appreciation to all of these workers for their cooperation in this effort to list the names of the soil series. The Bibliography of Soil Series Names reported to you as completed in 1933 has been repeatedly amended and, we are informed, will be published shortly in mimeographed form by the Bureau of Chemistry and Soils. This report will include the series reported below as well as those reported previously. It will be available to those having need for it.
