Brothers.' This wampum belt confirms our words. [...] Neither of us will make compulsory laws or interfere in the internal affairs of the other. Neither of us will try to steer the other's vessel. The treaty is considered by Haudenosaunee people to still be in effect. The Haudenosaunee tradition states:As long as the Sun shines upon this Earth, that is how long our Agreement will stand; Second, as long as the Water still flows; and Third, as long as the Grass Grows Green at a certain time of the year. Now we have Symbolized this Agreement and it shall be binding forever as long as Mother Earth is still in motion. The Wampum Belt(s) Wampum belts of the two-row style are merely one of many methods of representing in physical form the diplomatic and economic agreements implicit in the kaswentha relationship. There is clear evidence of Haudenosaunee use of wampum for diplomatic functions during the pre-contact period, while the post-contact period saw "increasing significance of wampum as a material form to facilitate communication across cultural boundaries". Early evidence for wampum in the region indicates that the dominant style was a relatively simple, monochrome design, often with discoidal beads strung together (rather than tubular beads woven together). Historians debate whether or not the technology required to construct the sophisticated two-row style wampum belt (including, most importantly, tubular purple beads) was available to communities in the region prior to 1613; however, Parmenter indicates that archeological evidence does not rule out the possibility that two-row wampum belts may have featured in the initial treaty negotiations between the Dutch and the Haudenosaunee. The significance of the two-row style of wampum, according to Parmenter, is that it captures the original "ship and canoe" metaphor present in the Haudenosaunee understanding of the kaswentha relationship. Parmenter explains how this "ship and canoe" metaphor is one of many "media" by which the Haudenosaunee have represented pictorially their relationship to European newcomers over the centuries, with other media including "a piece of tree bark or rope" and (later) images of an iron chain and, eventually, a burnished silver and/or covenant chain. But of these, it is the "ship and canoe" conception of the kaswentha relationship that is the deepest and most significant, and it is the two-row wampum that is understood to represent this conception most powerfully, with two rows of purple wampum beads against a background of white
