Whether the compass card on the Warren instrument was produced by Revere

is difficult to determine. Authorities on Revere's engravings agree that

it could have been engraved by Revere but are unable to state it

positively. It has been suggested that the entry in Revere's day book

indicates that he merely printed the compass cards for Warren and that

he did not engrave a plate. The charge for the work bears out this

supposition; and furthermore, Revere's bills seemed to make a definite

distinction between the engraving of plates and actual prints. Whether

or not Revere was responsible for making the original engraving remains

to be determined, but it is very probable that he printed the compass

card of the instrument in the Streeter Collection of Weights and

Measures at Yale.

_Daniel Burnap_

One of the best known and most respected names among Connecticut

clockmakers is that of Daniel Burnap (1759-1838) of East Windsor. Burnap

was born in Coventry in 1759 and served an apprenticeship with Thomas

Harland, clockmaker of Norwich. In about 1780 Burnap opened his own

establishment, where he combined the crafts of clockmaking,

cabinetmaking, and engraving of brass, in all of which he was greatly

skilled. One of his apprentices was Eli Terry, who later achieved fame

in the craft in his own right.[118]

Burnap's business included clients in Windsor, Hartford, and Coventry,

as well as some of the leading merchants and cabinetmakers of the nearby

cities and towns. Although clockmaking was the primary business in which

Burnap engaged, he also had a large trade for his surveying instruments,

silver spoons, gold beads, harness and saddlery hardware, and shoe

buckles.

Burnap prospered, and in about 1800 he moved back to his native town,

Coventry. There he purchased a large farm and erected a shop and a

sawmill, and in due course became the leading citizen of the community.

He died in 1838, leaving a valuable technological record in the

completeness of his journals and account books. A study of the entries

of his day books and ledgers (see fig. 64) reveals that Burnap did a

substantial amount of business in surveying compasses, chains, and

protractors. Among his shop equipment after his death there was found an

unfinished protractor, but no examples of his instruments are known

except for a compass dial, inscribed with his name, that was discovered

recently in the collection of a midwestern historical society.[119]

It is significant to note that Burnap made instruments of varying

quality. For instance, he charged three different prices for his

surveyor's compasses. The highest-priced compasses cost L6; they were

made of brass, and were of the more elaborate conventional type used by

surveyors. A few examples that appeared in his records cost L4; these

also were made of brass, but probably were of a simpler form. Several

entries list surveying compasses priced at L2 and L2/8. One of these was

made for Capt. Solomon Dewie (1750-1813) in September 1790 for L2/8. At

the same time, Burnap charged him L0/1/6 for touching the needle of

another compass.[120] The entries in Burnap's account books do not state

that these inexpensive compasses were constructed of wood, but it seems

to be sufficiently conclusive that they were.

_Gurdon Huntington_

Gurdon Huntington (1763-1804) was not primarily a maker of scientific

instruments, but he was established as a goldsmith and clockmaker. He

was born in Windham, Connecticut, on April 30, 1763, the son of

Hezekiah and Submit (Murdock) Huntington.[121]

[Illustration: Figure 64.--Entry in the manuscript ledgers of Daniel

Burnap (1759-1838) of East Windsor and Coventry, Connecticut, for sale

of surveying compass in 1790. Reproduced from the Burnap shop records in

the collection of Connecticut Historical Society, Hartford.]

The Huntington family was one of the most important in Connecticut

colonial history. Gurdon's father, Hezekiah, was in service during the

Revolutionary War, going to Boston as a major with the first troops

raised in Connecticut. When in Boston he witnessed the miserable

condition of the arms then in the hands of the soldiers. Major

Huntington went immediately to Philadelphia, where Congress was in

session, and proposed to the Congress that he would return to his home

in Windham and that there he would open a manufactory for repairing

muskets and other arms. He claimed to have been the first man to have

made a gun in the Colonies.

Gurdon was too young to have served in the Revolution, but he

undoubtedly worked in his father's gun manufactory as a boy. In due

course he learned the trades of goldsmith and clockmaker and established

his own shop in Windham, which, according to an advertisement (fig. 65)

in _The Connecticut Gazette_ of June 11, 1784, was "a few rods north of

Major Ebenezer Backus' store."

On Christmas Day, 1785, Gurdon was married in New London to Temperance

Williams of Groton. In 1789 their first child, Marvin, was born, and in

October of the same year the Huntingtons moved from Windham to Walpole,

New Hampshire. No reason can be found for the move, other than the

possibility that Gurdon might have anticipated greater opportunity in

the new community. There he applied himself to his trade as goldsmith

and clockmaker, but apparently he was not very successful. His family

grew, and by the time of his death there were eight children. Possibly

in an effort to supplement his income, Huntington served as postmaster

of the community. In about 1797, seven or eight years after he had moved

to Walpole, his father and mother joined him there, and it is believed

that Major Hezekiah may have worked as a gunsmith during that period.

Eventually the senior Huntington returned to Windham, Connecticut, where

he died in 1807.[122]

Meanwhile Gurdon Huntington struggled on until his death on July 26,

1804. He died insolvent, which created a considerable problem in view of

the large family he left behind him. Huntington's estate was

administered by Asa Sibley, a clockmaker in Walpole. Sibley had moved

to Walpole from his home in Woodstock, Connecticut, in the 1790's and he

remained there until 1808, when he again returned to Woodstock. Gurdon

Huntington's widow removed to Bloomfield, Ohio, with her children, and

she died there on May 25, 1823. Most of her children settled in

Bloomfield, but several of them moved to New Hartford, New York.

Several examples of Huntington's clocks are known to exist in private

collections in the United States. However, only one example of his

scientific instruments appears to have survived. This is a surveying

compass (fig. 66) made of wood, with brass sighting bars and a painted

dial under glass with a steel needle. The dial is inscribed "G.

HUNTINGTON/WALPOLE." The instrument, which is in the collection of the

writer, is made of cherry wood, with a riveted ball-and-socket joint of

brass for insertion on a tripod.

_Jedidiah Baldwin_

Jedidiah Baldwin (fl. 1790's) was another early New England clock and

instrument maker, but little is known of his early life. He was a

brother of Jabes Baldwin (c. 1777-1829), who worked as a clockmaker in

Salem and Boston after serving an apprenticeship with Thomas Harland in

Norwich, Connecticut.

Jedidiah Baldwin also served an apprenticeship with Harland. In 1791 he

was working in Northampton, Massachusetts, as a member of the firm of

Stiles and Baldwin, and from 1792 to 1794 he was a member of the firm of

Stiles and Storrs, in partnership with Nathan Storrs.[123] In about 1794

Baldwin moved to Hanover, New Hampshire, where he became the local

postmaster, and where Dartmouth College records his death.

Only one existing instrument is known to have been made by Baldwin; it

is a wooden surveying compass with a brass dial having two scales, one

for degrees and one for eight divisions per 90 deg.. The dial is inscribed

"JED BALDWIN/HANOVER." According to its present owner, Mr. Worth

Shampeny of Rochester, Vermont, the compass was used for surveying in

Vermont during the early 1800's.

Another Jedidiah Baldwin worked as a clockmaker in Morrisville, New

York, from 1818-1820 and then in Fairfield, New York; he appears also in

the city directory of Rochester, New York, as a clockmaker during the

years 1834-1844. He may have been a son or grandson of the first

Jedidiah, or a nephew.

_Thomas Salter Bowles_

Thomas Salter Bowles (c. 1765-?) is another elusive New England

instrument maker about whom little information is available. He is

believed to have been the son of Deacon Samuel and Hannah (Salter)

Bowles, born in Portsmouth, New Hampshire, probably between 1765 and

1770. His father was born in 1739; his mother, who was the daughter of

Captain Titus Salter, was born in 1748 and died in 1831.[124] Deacon

Bowles was clerk of the Brick Market in Portsmouth from 1801 to the time

of his death, November 3, 1802. There is a minimum of information

available from church and city records in the community, but it is

believed that he was a member of one of the offshoots of the established

Puritan Church, and hence he would not appear in its records. He kept

the lower school in the Brick School House on State Street for a number

of years.

It is believed that the Bowles family first came to Portsmouth during

the few years immediately before the beginning of the Revolutionary War.

It is known that a Thomas Bowles and a Samuel Bowles both signed the

Association Test on August 14, 1776, promising to oppose the hostile

proceedings of the British fleets and armies. Furthermore, one of the

principal taxpayers in Portsmouth in 1770 was a firm named Griffith and

Bowles, which paid L17 in taxes in 1770. The name of the Bowles who

formed part of this firm is not known, but it was either Samuel or the

first Thomas Bowles. The other partner was Nathaniel S. Griffith, a

watchmaker. It is possible that a tradition of instrument making existed

in the Bowles family even then.[125]

On file in the office of the City Clerk in Portsmouth are two

certificates of marriage made out by Thomas Salter Bowles. The first is

for his marriage to Hannah Ham, a ceremony performed on September 21,

1809, by Joseph Walton, one of the pastors of a church dissenting from

the Puritan regime. Hannah was the daughter of William Ham, a brother of

Supply Ham (1788-1862), a noted local clockmaker. Bowles may have served

an apprenticeship in that shop before he married Hannah. Two other

members of the Ham family--George Ham and Henry H. Ham--worked as

watchmakers in Portsmouth in the same period.

A search of the cemeteries has indicated that Hannah Ham Bowles died in

1811, age 20. She is buried with her infant son in North Cemetery.[126]

Thomas Bowles's second marriage certificate in Portsmouth is for his

marriage on September 29, 1813--two years after Hannah's death--to Abiah

Emerly Bradley of Haverhill, Massachusetts.

Little is known about the work of Bowles as an instrument maker except

through a few of his instruments. He is listed in the first Portsmouth

directory, of 1821, as a "mathematical instrument maker" with a place of

business on Daniel Street; his home was given as Austin Street in

Portsmouth. He did not appear in the city's directories of 1827 and

1834. It is assumed that he may have left Portsmouth in the interim,

possibly to settle in his wife's home town of Haverhill.

Three instruments signed by Bowles have survived, and all show signs of

considerable wear. They are surveying compasses made of walnut, having

maple sighting bars and a silvered brass vernier set under the glass.

Two examples, one in the Streeter Collection of Weights and Measures at

Yale University and one owned by this writer are almost identical in

size, form, and details. The only variation is that the Yale example

(fig. 67) has a bubble level under a brass strip set into one end, an

item lacking in the other example (fig. 68).

The compass card, made from a line engraving, is identical in each of

the three examples. A floriated fleur-de-lis on the North point has a

compass and square at its base, and the name T. S. BOWLES is on a riband

over it. Adorning the East point is an American eagle bearing a shield

with stars and stripes and clutching arrows in one claw and a laurel

twig in the other. In a ring within the central medallion is inscribed

(see fig. 68), "* T. S. BOWLES * PORTSMOUTH, N.H. *"

[Illustration: Figure 67.--Wooden surveying compass made by Thomas

Salter Bowles of Portsmouth, New Hampshire. With spirit level. Made of

birch, the compass is 13 in. long and has a diameter of 6 in. In the

Streeter Collection of Weights and Measures, Yale University.]

The most interesting of the three instruments was acquired by the

Dartmouth Museum as part of a collection of the late Frank C. Churchill,

an inspector in the Indian Service. The instrument (fig. 69) is a

quarter circle with a compass in its center and sighting bars mounted on

a swinging arm that reads the angle of the brass scale on the arc by

means of a vernier. It is mounted on a wooden tripod with the customary

ball-and-socket joint, which permits it to be placed on a vertical

plane. A built-in plumb bob at the side helps to establish the

vertical.[127]

Interesting features of this instrument are two inscriptions engraved on

the brass strip on the top of the dial. One states that it was "INVENTED

BY P. MERRILL ESQ." and the other relates that it was "MADE BY JOHN

KENNARD NEWMARKET." No information about P. Merrill has been found, and

it is presumed that it was he who conceived the idea of combining the

various elements into a single instrument and that it was made under his

direction by Kennard.

[Illustration: Figure 68.--Wooden surveying compass made by Thomas

Salter Bowles (1765/70-post 1821) of Portsmouth, New Hampshire. Made of

walnut, it is 12 in. long and has a diameter of 5-3/8 in. With walnut

sighting bars. In collection of writer.]

Bowles of Portsmouth. In Frank C. Churchill Collection, Dartmouth

College Museum, Hanover, New Hampshire.]

Some data on Kennard is available in a history of Newfields (formerly

Newmarket) by Reverend Fitts. John Kennard was born in Kittery, Maine,

in 1782. He learned the trade of clockmaker in Portsmouth, New

Hampshire, presumably working with the members of the Ham family or

others. On July 3, 1806, he married Sarah Ewer. He lived for various

periods in Nashua and Concord before moving to Newfields in 1812. He

lived in the Palmer house (which was burned in September 1899), and he

kept a store in the little community and also served as its postmaster

from 1822 to 1824. The post office was the only public office in the

town until the cotton mills were built on the Lamprey River in 1823.

Kennard later built and occupied the Kennard house on Piscassic Street,

which was subsequently owned by Jeremiah Towle and has since been

burned. In December 1830 he established an iron foundry together with

Temple Paul and the Drake family, but in 1834 he sold his interest to

Amos Paul and others. He was the father of six children and he died in

1861. During his lifetime he had specialized in making tall case and

banjo clocks.[128]

_The New Era_

The beginning of the 19th century saw increased trading and shipping

resulting from the economic development of the new republic, and the

westward surge brought increased preoccupation with the settlement of

communities and the development of land areas. As a consequence, the

demand for instruments likewise increased.

Whereas during the 18th century and until some time after the end of the

Revolutionary War probably not more than a dozen instrument makers and

dealers are known to have emigrated from England or elsewhere to make

their homes and careers in the American Colonies, the beginning of the

19th century saw substantial numbers of English and French instrument

makers and dealers immigrate to the United States, to establish shops in

the major centers of trade.

And whereas the names of scarcely a hundred mathematical-instrument

makers who worked in the American Colonies during the 18th century are

known today, the names of hundreds of similar 19th-century craftsmen and

dealers are to be found.

As Derek Price[129] has so cogently stated: "For scientific instrument

makers, one need only examine the nineteenth century city directories of

Boston, Philadelphia and New York to find hundreds of names of craftsmen

and firms. It is, to be sure, an antiquarian research, for one does not

expect to find great discoveries coming from these people. But just as

in Europe, it is a populous trade, influential in the growth of science

and highly effective in spreading and intensifying the itch for

ingenious instruments and devices. It is by these men that the basic

skills of the Industrial Revolution were populated...." By such means

did American science and technology come of age.

George Adams (1704-1773) was mathematical instrument maker to King

George III. After serving an apprenticeship from 1718, he made

instruments for the East India Company in 1735 and 1736, and established

a shop at "Tycho Brahe's Head" at the corner of Raquet Court, Fleet

Street. He specialized in terrestrial and celestial globes and

microscopes. Following his death he was succeeded in business by his son

George Adams the Younger (1750-1795), who also served as

mathematical-instrument maker to the king.

This instrument is believed by the donor to have been used by either

Andrew Ellicott or by his son-in-law David Bates Douglass.

The firm of "W. & S. Jones" was a partnership of two brothers, Samuel

and William Jones, opticians, who worked at 30 Lower Holborn and at 135

Holborn in London, from 1793. They bought the copyright to the books of

George Adams, and subsequently largely carried on the original business

of the Adams instrument makers.

In _The Journal of Andrew Ellicott_ its author describes this instrument

as the first of "Two Acromatic Telescopes for Taking signals, with

sliding tubes, one of them drew out to upwards of 4 feet, and the other

to about 15 inches, the latter for its length is remarkably good, it
