Haiku in English circular form (sometimes known as "cirku") whereby the poem has no fixed start or end point. In the "zip" form developed by John Carley, a haiku of 15 syllables is presented over two lines, each of which contains one internal caesura represented by a double space. A fixed-form 5-3-5 syllable (or 3-5-3 word) haiku is sometimes known as a "lune". The leading English-language haiku journals published in the U.S. include "Modern Haiku", "Frogpond" (published by the Haiku Society of America), "Mayfly" (founded by Randy and Shirley Brooks in 1986), "Acorn" (founded by A.

Haiku theoretician F. S. Flint, who passed on Couchoud's ideas to other members of the proto-Imagist Poets' Club such as Ezra Pound. Amy Lowell made a trip to London to meet Pound and find out about haiku. She returned to the United States where she worked to interest others in this "new" form. Haiku subsequently had a considerable influence on Imagists in the 1910s, notably Pound's "In a Station of the Metro" of 1913, but, notwithstanding several efforts by Yone Noguchi to explain "the hokku spirit", there was as yet little understanding of the form and its history.
