angular lagoons within ; and with some of them it is an open 
question whether they were formed as recurved spits, or as two 
spits converging outward by simultaneous growth. Some evi- 
dently have the former origin, as the opening into the lagoon 
can be seen near the base of one side. Others show no such 
gap, and certainly appear to have been formed by the latter 
method. 
Of the former class are South bar, on the south side of 
Sidney harbor, described by Prof. Tarr ; Allen point, north 
shore of Northwest Arm, four miles from the last; several, for 
the most part unnamed, on the south side of St. Andrew chan- 
nel ; northwest of Shenacadie, near the west end of Little Bras 
d'Or proper ; six miles northeast of the last, forming the west 
side of Beaver cove ; and Macdougal point and its eastward 
extension, northeast side of East bay — a fine example. These 
varieties grade gradually into ordinary recurved and hooked 
spits. 
Of the cusps which have a closed lagoon, one of the best 
is Kelley point, northwest end of Barra strait. Others are a 
mile east of Porphyry point, East bay; Carey point, eastern 
part of Great Bras d'Or, which is in a sense intermediate, hav- 
ing at times a small outlet near the apex ; Lockman point, St. 
Andrew channel, at the settlement of Boisdale ; Dougal point, 
three miles northeast of the last ; Big pond, southwest end of 
West bay ; and Grande Greve, St. Peters bay. 
Modifications of this form, as bluntly curved promontories 
projecting from an essentially straight shore and holding a 
lagoon, are found in Long beach, south of Seal id., in the nar- 
row east end of Great Bras d'Or, which is the onlv case large 
enough to be given a name. At the east end of St. Patrick 
channel, two miles east of Murphy point on the south shore, 
is a smaller but well formed one. Early stages in the growth of 
closed cusps can be seen, showing two converging spits with 
a lagoon between, as the bars inclosing Goose pond, southwest 
shore of Little Bras d'Or, six miles east of Barra strait ; and 
Maclean beach, four miles east of Shenacadie. 
Loop bars. — Bars inclosing lagoons on the leeward side of 
islands are common. Examples are the northeast end of Kid- 
ston id., Baddeck bay ; the west and south ends of Macdonald 
id., Whycocomagh bay, the latter compound ; the west end
