四川方言词源 has the following information under the entry for 搊贺:
又，下江人《释四川话(二)》： “救济□人，或扶助他人成 功，称为‘抽合’。”(《旅行杂志》1945/7/18)此记音。
The article is then referenced again under the entry for 打启发:
又，下江人 《释四川话 (二)》： “打抽丰称 ‘打起发’。” (《旅行杂志》1945/7/18)
CADAL (China Academic Digital Associative Library) has an issue here: 旅行杂志
which apparently works out to:
then the next part says:
Vol. 19/NO. 7
but the table of contents also says:
I'm not sure what 四川方言词源's reference of《旅行杂志》1945/7/18 exactly means. 1945 is the year; if 7 is the month that corroborates with the issue on CADAL which says 七月 on the cover.
p. 2 says:
Does that mean 《旅行杂志》1945/7/18 would be the earlier issue: Vol. 19/No. 6?
but then that article says:
Vol. 19/No. 6
1945 Vol. 19/No. 7 does have an article titled:《释四川话》| the reference in 四川方言词源 says《释四川话 (二)》though - with a #2. I'm struggling to figure this out though.
another example of a reference from the same book looks like this:
白虹《四川方言 (川行杂记之 六)》： “锅块，烧饼也。” (《自修》 1941/162/24)
'41 is most likely the year
