The references contained in this bulletin were compiled in connec- 
tion with an investigation by the Bureau of Public Roads of the effect 
of soil alkalies on concrete drain tile. The bibliography is believed to 
be fairly complete in respect to articles published prior to 1924. The 
importance of the problem presented by the use of concrete structures 
in sea water and in soils containing various acids and alkalies has long 
been recognized. To one engaged in the study of any phase of the 
problem the literature extant 1s indispensable. Such a compilation 
necessarily requires considerable time and labor, and in order that the 
results of this search may be made accessible to as many as possible 
the bibliography is published as a bulletin. 
EXPLANATORY NOTES 
The references are arranged alphabetically by authors under each of 
the six headings. Each article is placed under the heading which 
most nearly describes its main content and those which fall under 
more than one heading are cross-indexed. The Roman numerals used | 
in connection with authors’ names indicate the headings under which | 
the cross-indexed references appear. Plural authorship is cross- 
indexed in a like manner. At the end of the groups are lists of refer- 
ences, arranged alphabetically by titles, referring to articles the — 
authorship of which is not indicated. These are also cross-indexed by | 
Roman numerals. The abstract in each case refers to the first refer- 
ence given under the title. The other references under a given title | 
may or may not be of the same title, but are concerned with the same | 
subject matter. Inclusive paging is not always given for these 
supplementary references. |
