It is also able to maintain itself perfectly where salt marsh turf has overlaid the shingle to a depth of 1 or 2 feet. Occasionally it is found sporadically on salt marshes, apparently quite inde-

In ordinary garden soil, and even in a London window-box, it flourishes amazingly. When better known, Suaeda will doubtless be cultivated as an ornamental shrub.
