For the year 1914 in my great-grandfathers Civil Guard records there are five entries.
Here is the second note (it spans two pages):
I am assuming that we might be hitting entries pertaining to the first world war as I see his soldier number again. But in all honesty I have found this note to be too hard to read. I can only make out a small number of words. As I result I have not attempted to display an initial transcription because there would be many XXX words.
Translation
Translation so far:
Fulfilling this indº (individual) his commitment nº 19.647 at the end of August marginal year, he requested and was granted by the 1st Chief of his Command a new reenlistment for four years with option to the benefits granted by the current Regulations but without prejudice to what the Intervention General resolves to terminate (?) the same on 1 September of this year and will terminate it at the end of August 1918, during which time he will enjoy the daily bonus of 25 centimes of peseta, and in proof of his agreement he signs this note before the undersigned Chief and witnesses.
Update 1
Updated the translation to take into account the suggested word mentioned in the comments to the answer.
Update 2
I split the translation into two parts when using DeepL and have updated the translation. I think it still needs improving though.
