1866 Partridge Island, Canada
for a Report on the meteorology of [[mine?]] the Report of the main Board of Agriculture for 1865. [[in pencil]] Does sound travel faster in a wind [[/in pencil]] [[overwritten in ink]] Is the velocity of sound greater in a wind in the same direction than in a calm or in a wind in an opposite direction? This has not yet been determined [[/overwritten in ink]] [[end page]] [[start page]] [[page number in pencil]] 1 Electrical light by the Board of Trade. was introduced 1858 at South Foreland - was transferred to Dungeness June 1862 since then until (1866) now it has been used The old apparatus is always kept ready in case of accident and with good cause Between June 63 and Dec 64 the light failed for an agregate period of 119 one hundred and nineteen 1/2 hours. The light part is the least liable to fail want of steam of water neglect are cause of failure
on the whole the opinion of the Elder Bretheren is not favourable to this light. They however intend to give it more time. The latest novelty in the way of illumination is the Electromagnetic apparatus of the [[wilds?]] of Manchester an account of this has been given to the Royal society [[end page]] [[start page]] [[page number in pencil]] 3 [[image - hand-drawn in ink]] The length of time the tube is shut depends on the side pieces [[image - hand-drawn in ink - a speaking trumpet]] The effects of the speaking trumpet is said not to be due to reflections by [[cause?]] the flaring part produces a marked effect which it could not do on principle of reflection [[image - hand-drawn in ink - long cylindrical tube with a flared end]] a cylindrical tube with a flare produces same effect The material paper or tin

Mr Foster's return on Roper's Engine etc Is opposed to the whole trumpet system The trumpet he thinks gives more sound [[near?]] by but cannot be heard as far It affects the ear when near but can be heard at a less distance in foggy weather - not so penetrating Thinks the engine may be improved so as not to be so liable to get out of order under the change of ordinary [[end page]] [[start page]] [[page number in pencil]] 7 Roper thinks it will break down with ordinary usage Packing of leather requires frequent renewall unless constantly oiled It requires four times as much oil [[insertion]] as [[/insertion]] any [[strikethrough]] other [[/strikethrough]] engine driven by steam The faster an engine goes in any of its parts the greater the quantity of oil required The valves are liable to be burned out by a little over heating great care required on this account Valves very difficult to replace A Fog signal like in
after being started must suffer no interruption There should be furnished duplicate parts which can readily be substituted for any that may give out After all he thinks Roper's Engine better than Erickson's - Both in his opinion are going ^[[insertion]] out [[/insertion]] of use in Boston and in Portland - Not on account of the fuel used but the expense of repairs and renewall of parts. They do not do as much work ordinarily as they are rated to do. [[end page]] [[start page]] [[page number in pencil]] 9 The arrangement for opening the valves of the trumpet is defective [[strikethrough]] It must move a [[/strikethrough]] The ratchet wheel must move with so much friction on its axis to enable it to hold its own that it impedes the engine and is liable to be broken as it was in this case Mr Foster thinks an ordinary steam engine with boilers with large steam space and little water surface would be surely managed not liable to get out of order No difficulty in regard to
water for the boiler at this place there is an unfailing or spring near from which water can be conducted. The same may be said of other places were fog signals are required on this coast The proposition has been made to catch water for the boiler in tanks but this must be doubtful and will depend on [the?]] amount of rain. The experiment of boiling down a quantity should be made [[end page]] [[start page]] [[page number in pencil]] 11 The opening on the 3 sides of the steel towers according to Mr Ropers measurment, is about 1/32 of an inch average and 6 inches long while on the six inch steam whistle it is 18 inches long and at least 1/32 of an inch in width if not more Hence under the same pressure the power to blow the whistle will be three times as great but the whistle was not heard as far with nearly double the pressure
I have directed Mr Case to work this house as long as it continues in order every foggy day The object being not to satisfy the steam boat owners that the trumpet is sufficient for this place but the Board as to the operation of the Roper Engine as to continuance in good order [[end page]] [[start page]] [[page number in pencil]] 13 Mr. Ropers informs me that he will construct to one house engines for 10.00 dollars each all properly equipped Sept - 25th 1866 Left East Port in the Steamer New England. Capt Field Recieved us very politely the Capt has heard the trumpets at Quoddy for 4 or 5 minutes which at this rate of sailing 12 miles an hour would give about a mile. The pilot of the New England Capt. Long as he is called says he has heard
the gun at Quoddy head 5 miles wide favourable conditions with a strong wind a head not more than 2 1/2 miles - Can hear the bell with a fair wind 3 1/2 miles when rung by hand. Has [[?]] sound of Trumpet at distance of one and a half miles says the horn on Thatchers Island can be heard a distance of 2 miles [[end page]] [[start page]] [[page number in pencil]] 15 under favourable circumstances Could hear the steam apparatus on Partridge Island near St John 8 miles could as first hear it 12 miles It is now not in as good condition as at first. It has been in operation about 7 years blows about once in a minute was constructed by Messrs Hemming
and Humbert of St John. Before the steam apparatus was put up a Gong of large size four feet in diameter was beaten but this though giving a very disagreeable sound near by was not sufficiently powerful at a distance There is no difficulty in regard to the conforming of the steam apparatus with the whistle of [[end page]] [[start page]] [[page number in pencil]] 17 the locomotive the distinction can be made evident by the regularity of the blowing at stated intervals Off Partridge Island passed a floating hull Gong which has been in service about 10 years except where laid up for a year or two. The Light House as this place is now lighted with paraphine was for some years lighted by coal gas.
For an accurate account of the occurrence of the Fogs at this station see table given me by G.W.Smith of the custom [[?]] the Bay of [[Fundee?]] The Fog comes in with a wind directly from the south. According to Mr Edwards of the Light House service from Portland to Mount [[Desert?]] the fog comes in from the south round to the east According to Mr Foster from S.S.W to E.N.E that is from 2 points W of South to 2 points [[end page]] [[start page]] [[page number in pencil]] 19 [[strikethrough]] W of South E of 2 [[/strikethrough]] N of E Beyond there to the North or west the wind blows off the Fog A breeze from this land always takes off the fog Between the above mentioned points we always look for clear weather Mr Edwards has seen the fog stopped
by Grand Manan Island according to Mr Foster the further we go south along our coast the wider is the arch of the Eastern horizon [[underlined]] from [[/underlined]] which this fog comes Capt Tarr of Glouster states that from all he had learned there was little or no Fog in the Islands in the mouth of St [[strikethrough]] La[[/strikethrough]] Lauerence. There is scarcely a single [[end page]] [[start page]] [[page number in pencil]] 21 foggy day in a year on Prince Edwards Island though there is much cloudy weather That there should be little or no foggy weather on this Island is not surprising when we reflect upon its position relative to the gulf stream and Nova Scotia The same gentleman informs me that there is more cloudy days and less rainy
ones on this Island than on an equal surface in the United States. The sound of the breakers is a great obstruction to the sound of the bell or the trumpet at Quoddy Head. Besides this the fog arrives at this place almost always with a strong adverse wind not so at [[Bannistail?]] [[end page]] [[start page]] [[page number in pencil]] 23 Sept 26th Called at the works of Hemming and Humbert casters the makers of the Fog apparatus at Partridge Island was improved there Robert Fondis an old Scotchman was the inventor Mr Hemming's son said he thought a patent had been taken for it but the inventor was dead and had been buried at the public expence. The machine can be run by an ordinary fire man. It is proposed to put up an other on an improved
plan The boiler to be an upright one This would double the fire surface and enable the steam to be sooner got up This would be on the [[plan?]] of the fire engine which is ready for operation in 15 minutes. The pressure apparatus was put up in Nov 1859 and up to this time has been continually at work without intermission. For 3 years no repairs what ever were [[made?]] since then there the whole amount of charge for repairs has been 38 dollars. [[end page]] [[start page]] [[page number in pencil]] 25 There has been been some difficulty in obtaining the proper suppy of water on the Island The Light House on Partridge Island was for several years illuminated by coal gas but this has been abandoned on account of the trouble and expense. The material now used is paraphene now which costs $2.60 per gallon Formerly seal oil was used in summer and porpoise oil in winter
the latter resists much better the freezing. The NB In the new currency of Newbrunswick 4 dollars.

The Light Houses of this Bay are under the direction of six commissioners four of whom reside in St John Seal oil was used in the Summer porpoise in winter were used now

when in operation the apparatus requires constant attendance and two watches are kept of 6 hours each A watch is also continually kept in clear weather for the approach of a fog which can be seen 10 miles off. A vessel ought not to be endangered from a fog for half an hour after it is formed during that the change of [[end page]] [[start page]] [[page number in pencil]] 37 [[/page number]] position if well determined cannot be so great as to endanger it.

If limy will encrust and injure the boiler cannot be scaled off too small to get in. water should be blown off the boiler after use and the metal kept dry to prevent rusting, Mr Roper could not hear the whistle 3/5 of a mile and found the interval 1 1/4 minutes [[end page]] [[start page]] [[page number in pencil]] 47 Mr Roper proposes that we increase the air chamber of the engine 4 times. also to increase the interval and thus to increase the capacity of the horn. It is understood that the engine now at Portland intended for Boon Island is to be sent to [[strikethrough]] [[?]] [[/strikethrough]] [[insertion]] Mr Ropers [[/insertion]]and supplied with
an additional air chamber in increasing its capacity to 4 times Then two mouth pieces to be made one with a single and another with a double read The quantity of water used was nearly 48 cubic feet per 8 hours or 6 feet per hour equal to a six horse power engine. The blowing taking place [[end page]] [[start page]] [[page number in pencil]] 49 In the use of the Steam Boiler a supply of pure water must be had otherwise the apparatus will soon get out of order [[line]] once in a minute instead of 3 times gives 18 times the power of the steam required to blow the whistle more than the trumpet
Mr [[Winn?]] of Portland a man of reputation thinks the [[arm? arc?]] engines will go out of use on account of difficulty in keeping them in repair they will not be used were steam power can be obtained This agrees with the statement of Mr Foster [[end page]] [[start page]] [[page number in pencil]] 51 The relative power required to blow the two signals may be obtained as follows [[line]] The whistle has steam at 90 lbs per inch - The trumpet air at 15 -- The whistle blows once in a minute the whistle 3 times a minute - Hence 3 x 15 = 45: power for trumpet 1 x 90 = 90: " [[ditto for: power]] for whistle [[strikethrough]] but 45/3 = one blow of trump 15 : 90 = 6 [[/strikethrough]]
The whistle requires [[overwritten]] 3 [[/overwritten]] 6 times the pressure and blows 1/3 as often hence the ratio of the power is 18 to one.

Capt. Moses Tarr of Gloster Has heard the Trumpet on Thatcher island Cape Ann for a year or two and have always heard it when it was blown at a distance of six miles at Glouster He has also heard the bell which is about 3 miles distant The Trumpet is about East - the bell is about S.S.W. [[end page]] [[start page]] [[page number in pencil]] 55 Capt Tarr thinks that the trumpet is heard best with the wind at right angles to the direction of the sound Can get 50 persons to testify Rain does not clear off a Fog If rain occurs during fog although the air may be a little clearer at the time it becomes thicker afterward

The pressure at Bevertail was not more than 10 lbs to the inch [[pencil writing overwritten by ink account:]] G. Washington Street St John, NB [[/pencil]] When a strong wind blew from the north thinks there is more power can start the engine quicker The steam trumpet at Bevertail had a number of reads which could be substituted one for another [[end page]] [[start page]] [[page number in pencil]] 65 Engine was not at first properly put up it waisted a large amount of air. Has run the engine continuously for six days. An attempt was made some years ago to blow a wistle by steam. An upright boiler 8 1/2 feet high standing on an ash [[prop? pipe?]] 18 inches high filled with 105 tubes 8 feet long & about 2 inches in diameter was used Took about 3/4 of an hour to get up steam The project came to nought on account of the want of water
The pumping and operation the values were performed by a small scillating engine. An Artezean well was bored which at first yielded 26 an hour then declined and after a while gave none After standing it gave water again but this was only the superficial water which ran in gradually 36 gallons per hour are required for the boiler The ordinary well gives out in very dry weather have then to go an 1/8 of a mile for water [[end page]] [[start page]] [[page number in pencil]] 67 Thinks the well would furnish enough water for a boiler by constructing an underground tank or reservoir to be filled from this well by means of a windmill pum The well daily would furnish watter for 9 months in the year Proposition to put up sheds to catch the water The artezean well is 85 feet deep the other well is 26 feet
Whitewashed rocks are used as beacons in the bay near New Port I am informed by Capt Macy that the natives of the Marquesas Islands catch porpoise by going out beyond the breakers and striking stones together underwater for this purpose they jump overboard The steam whistles in the streets of New York are a nuisance, the trumpet ought to be used with it. [[end page]] [[start page]] [[page number in pencil]] 65 Mr Kinsman informs me that the sound of the breakers at Quoddy Head drowns that of the fog signal. Will the whistle give the same sound when placed vertically as one placed horizontally [[image - hand-drawn in ink - a trumpet for a whistle]] The flaring part of the trumpet was may vibrate [[latterly?]] when made of thin metal
