Repointing stone wall in basement

I was wondering if anyone knows anything about stone wall foundation/basement walls in >100 year old homes. I am a bit confused about the mortar used in my basement walls. It looks like it is something mixed with the dirt from our area (reddish dirt). Its quite soft and comes out very easily in some areas.

I'd really like to repoint the stone walls for sealing, etc but I'd like to know a bit more about what is currently there first to know if I need to dig out the old or just repoint the outer 1"+.

Our house is an 1870's row house and last sprint in an unprecedented rain our basement walls started to leak in some areas which brought up the problem. I plan to seal some cracks but want to do it all right.

If anyone can point me to further reading, has any idea what our mortar might be or how to approach it, we'd be greatly appreciative.
