Answer: Dactylic meter.
Explanation:
In poetry, <em>meter</em> is the pattern of the beats. It is also referred to as a 'foot'. There are certain number of syllables in each foot (often two or three). Different types of meter have different patterns of stressed/unstressed syllables.
Dactyl meter, found in these lines from Robert Browning's poem <em>"The Lost Leader"</em>, has the first syllable stressed and the second and third unstressed.  The pattern is the following:
<em>Just</em><em> for a </em><em>hand</em><em>ful of </em><em>sil</em><em>ver he </em><em>left</em><em> us
</em>
<em>Just</em><em> for a</em><em> rib</em><em>and to </em><em>stick</em><em> in his </em><em>coat.</em>
