What is Ichabod Crane's job in "The Legend of Sleepy Hollow"?

Ichabod
Crane is a schoolteacher in the town of Sleepy Hollow.  Here is the quote stating
this:

• Ichabod Crane, who sojourned, or, as he expressed
  it, "tarried," in Sleepy Hollow, for the purpose of instructing the children of the
  vicinity.

  He is not the most fair or proper schoolmaster, however.  He
  disciplines his children not based on their offenses, but based on their stature.  The same
  offense may be committed by a weak and a strong child, but the strong child will get the
  harshest punishment:

  • on the contrary, he administered
    justice with discrimination rather than severity; taking the burden off the backs of the weak,
    and laying it on those of the strong. Your mere puny stripling, that winced at the least
    flourish of the rod, was passed by with indulgence; but the claims of justice were satisfied by
    inflicting a double portion on some little tough wrong-headed, broad-skirted Dutch urchin, who
    sulked and swelled and grew dogged and sullen beneath the birch.

    He was fond
    of walking his young students home.  Not for their own safety, however, but in hopes of getting
    some good food from their mothers or in hopes of spending time with good-looking older
    sisters.

    • and on holiday afternoons would convoy some of
      the smaller ones home, who happened to have pretty sisters, or good housewives for
      mothers
