The following paper includes observations thai have been mad.' on the marine sVlgaa 
N •. Brunswick during the past i\\<> years, together with Borne remarks <>n their 
nomic value, the occurrence of some rare Bpecies, etc. The localities visited have been 
various points on the southern shore of New Brunswick, including the Island of Grand 
sfanan, and the 1 m uaquel and Trai adie, with the Island- of Shippegan and Mi- on 

on the Gulf of St. Lawrence. To this is appended a preliminary list of the marine Algae 
of the Maritime Provinces, which the writer, with the assistance of Mr. A II. afacKay, 
of Pictou, li 'iily compiled for the Natural History Society of New Brunswick. Tin- 

list includes some eighty species of marine Algae, which, with the exception of an Intro- 
troductory List of New Brunswick Algae, published I>y the writer in L886. is the Rrsl 
attempt to arrange our Algic flora in such a form as shall lead to a closer investigation of 
these interesting plants, and stimulate further study in this direction. No Diatomaceous 
or other microscopic forms are included in the subjoined list, bul only those which may 
be easily detected by the eye, including chiefly the larger forms and those parasitic npon 
them. I mentioned in Dr. Farlow's " Marine Algae of New England," there

the rocks for miles are clothed with them. On the sandy shores of the Gulf of St. Law- 
rence, the Fuci miss the rocks which afford them a substantial foothold, and are of rarer 
occurrence. The zone of the Laminarise extends from low-water mark to several fathoms 
in depth. They occur in greatest profusion on the Gulf of St. Lawrence coast, where, after 
a southerly gale, vast masses thrown up by the waves may be observed for miles along 
the shore. On the southern coast their occurrence is somewhat rare for a considerable 
distance east and west of St. John, probably owing to the strength of the tides which 
sweep them from their resting-places. Towards the mouth of the bay, however, they 
occur in greater abundance. 

Only two forms of Fucus are common on the coast of New Brunswick, viz., Fucus 
nodosus {Ascophyllum nodosum) and F. vesiadosus. These two species form nearly the whole 
covering of tidal rocks in the vicinity of St. John, and westward to Passamaquoddy Bay. 
Dr. Harvey, in his introduction to the " Nereis Boreali- Americana," remarks on the poverty 
of species of Fucus on the north-east coast of America, compared with the northern coasts 
of Europe. Of the four species found in abundance in Europe, two of these, F. serralus 
and F. canaliculatus, had not been found in America at the time of Harvey's visit in 1850. 
The latter has not yet occurred here. The former is mentioned in the supplement to the 
" Nereis " as having been found at Newburyport, Mass., but has not since been detected 
there or at any other point on the New England coast. A specimen of this plant, collected 
at Pictou by Rev. Prof. Fowler in 1869, is in the Natural History Society's Herbarium in 
St. John. It has not yet been reported from the New Brunswick coast. Two other spe- 
cies of Fucus occur here, confined as yet to a single locality for each, although they may 
be expected elsewhere, as Dr. Farlow describes them as common on the New England 
coast, viz., F. evanescens 1 found at Frye's Island, and F. furcatus just below low- water mark 
on the flat shores on the north-west side of Miscou Island. These two species have not 
yet been reported from Nova Scotia. 

Although the Fuci are excellent fertilisers, very little use is made of them in that 
respect in New Brunswick. Near the southern coast of the province they are used to a 
limited extent on grass lands. I noticed some fine fields of grass on Grand Manan, last 
August, w T here these plants had been used as a top-dressing. Applied fresh to the land 
after the grass has been cut, and kept moist by the fogs which prevail there, they rapidly 
decompose and melt into the ground. The experience of those who have used them for 
fertilising purposes goes to prove that they yield the best results when used fresh. Their 
value as fertilisers is diminished, if used for other than grass crops ; or if carted for any 
considerable distance from shore, owing to the expense of conveying so bulky a material. 
In some countries (Ireland and Scotland), crops of potatoes are raised by their means, but 
the crops thus yielded, though abundant, are of coarse and inferior quality. The ashes of 
the Fuci contain a large quantity of carbonate of soda ; and Dr. Harvey states that they 
were once cultivated on the shores of Scotland, where rocks were deposited to attract them 
to sandy or pebbly shores. The total amount of revenue, says the same author, derived by 
the proprietors of these kelp shores on the coast of Scotland, during the eighty years from 
A.D. 1*720 to 1800, was .£595,000. But this trade was long since destroyed by obtaining

recognise them, might, in the case of shipwrecked mariners, be of great value in sustaining 
life for a considerable time. 

Among the rarer forms of Algae that occur on our coast the following may be men- 
tioned as worthy of notice : — 

Utothrix collabens, a small green Alga, found occurring at intervals on the inner shores 
of Miscou and Shippegan. This is a beautiful species, with tufted slender filaments of 
dark green, and does not occur on our southern shores, and but rarely in New England. 

Odonthalia dentata, though found at various points on the Gulf of St. Lawrence, and on 
the southern shores of Nova Scotia and New Brunswick, has not yet been detected on the 
New England coast. It is a very attractive species, of a deep red color, and occurs on 
rocks and stones in deep water. 

Polysiphonia fibrillosa, found oil the north side of the Island of Miscou in considerable 
abundance, has hitherto been detected only at one place north of Cape Cod, referred to by 
Dr. Harvey in the " Nereis." It is one of the most beautiful species of Polysiphonia, and 
growing abundantly in tufts in shallow water, is a delicate and attractive form. Another 
species that is collected for its beauty, although not a rare species, is CaUithamnion Pylascci, 
which I detected at Grand Manan, although I have not observed it at any point east of 
that station. Its occurrence, as well as that of forms common on the New England coast, 
may be expected on further investigation.

on taking charge, of chemistry on his arrival at Halifax he could get no rubber 
tubing in the city. "While his order was coming, he used the hollow stipes of this 
seaweed, which is always cast up in abundance on the Halifax coast, and found 
it to answer splendidly for the conduction of gas, MacKay. Around Grand 
Manan and the southern coast of New Brunswick the forms of Laminarise are 
variable and confusing, the two following species (L. saccharina and L. digituta) 
being most abundant, Hay.
