Who or what was last on the list of items to be saved from a fire, according to Mark Twain?

If it's a boardinghouse that's on fire, "the unclassified."

Copy-and-paste:

In assisting at a fire in a boarding house, the true gentleman will always save the young ladies first--making no distinction in favor of personal attractions, or social eminence, or pecuniary prominence--but taking them as they come, and firing them out with as much celerity as shall be consistent with decorum. There are exceptions, of course, to all rules; the exceptions to this one are:

Partiality, in the matter of rescue, to be shown to:

1. Fiancees.
2. Persons toward whom the operator feels a tender sentiment, but has not yet declared himself.
3. Sisters
4. Stepsisters
5. Nieces
6. First Cousins
7. Cripples
8. Second Cousins
9. Invalids
10. Young lady relations by marriage
11. Third cousins, and young lady friends of the family
12. The unclassified

Parties belonging to these twelve divisions should be saved in the order in which they are named.

Twain intended this to be humorous, and was poking fun at etiquette books.

Further down the page is a continuation of the list beyond the twelve categories of young ladies. Presumably, after they have been taken care of, one can rescue other 'items', the last of which is mothers-in-law.

"Other material in the boarding house is to be rescued in the following order:

13. Babies
14. Children under 10 years of age.
15. Young widows
16. Young married females
17. Elderly married ditto.
18. Elderly widows.
19. Clergymen.
20. Boarders in general.
21. Female domestics.
22. Male ditto.
23. Landlady.
24. Landlord.
25. Firemen.
26. Furniture.
27. Mothers in law."

Indeed, Looney. And I just noticed at the bottom of THIS page

What came last on Mark Twain's list of 27 things to rescue in the event of a boardinghouse fire?

Mothers-in-Law (anagram of "Women Hitlers")

Mothers-in-Law is NOT an anagram of Women Hitlers (the link above led to a URL not found message). Woman Hitlers, yes.

No link, as I am simply correcting information from an unavailable link!

But this series of answers should be kept as it now includes a correction to an earlier posting.
