For those that hunt deer or any kind of game and when the kill is made throw away the hide, because of the expense to have the hide tanned there is another way, the American Indians taught us this.
Strip the hide, be it moose, rabbit, squirrel, deer or bear.
Let stand in the sun for one week, bring in at night to keep it dry.
Cover with a foot or so of ashes preferablbly OAK but most any ash will do.
Bury it in a dry area for 3 months, dig it up and begin the stretching of the pelt and the scraping of the inside of the hide. it will take a month or more to get he hide flexable enough to be made into garments, shoes, or blankets.
A good thing or a bad thing , who knows, when we went west and wiped out the Buffalo herds counted in the millions, the bones were sent East to be ground up into fertilizer that gave a big punch to the mid western soil, that area is now our bread basket and feeds the world.
Who knows what any ashes will be valuable, in a future time of Sci-Fi, it may be that there are no more cemetery's, the ashes of the deceased may unlock a time of use for prevention of disease or a new way to feed the world with a new fertiliser.
There is a reason why we speak of ASHES to ASHES, perhaps we are not paying attention.
