   Note: Through ignorance or carelessness speakers and writers
         often confuse the forms of the two distinct verbs lay
         and lie. Lay is a transitive verb, and has for its
         preterit laid; as, he told me to lay it down, and I
         laid it down. Lie is intransitive, and has for its
         preterit lay; as, he told me to lie down, and I lay
         down. Some persons blunder by using laid for the
         preterit of lie; as, he told me to lie down, and I laid
         down. So persons often say incorrectly, the ship laid
         at anchor; they laid by during the storm; the book was
         laying on the shelf, etc. It is only necessary to
         remember, in all such cases, that laid is the preterit
         of lay, and not of lie.
