The key concept is that heat is a form of energy corresponding to a definite amount of mechanical work.

Heat was not formally recognized as a form of energy until about 1798 when Count Rumford A British military engineer noticed that limitless amounts of heat could be generated in the boring of cannon barrels and that the amount of heat generated is proportional to the work done turning a blunt boring tool.

Rumford's observation of the proportionality between heat generated and work done lies at the foundation of thermodynamics.

Another pioneer was the French military engineer, Sadie Carnot, as we said, who introduced the concept of the heat engine cycle and the principle of reversibility in 1824.

Carnot's work concerned the limitations on the maximum amount of work that can be obtained from a steam engine operating with a high temperature heat transfer as its driving force.

Especially in the Colonial Period was the temptation great to include more early American verse.

Peter Folger's A Looking-Glass for the Times, Benjamin Thompson's New England's Crisis, Michael Wigglesworth's God's Controversy with New England, The Sot-Weed Factor, and many others, which it is recalling an old sorrow to name here, were excluded only after long and bitter debate.

No doubt other exclusions will be noticed by nearly every reader of the volume, and it may interest him to know that the material gathered together would have made four such books as this.

The thread of narrative upon which the poems have been strung together has been made as slight as possible, just strong enough to carry the reader understandingly from one poem to the next.

These brave essays draw forth male stronger hands.

More like to daubers than to martial bands These do the work the sturdy bulwarks raise, But the beginners well deserve the praise.

The improvements in the printing press and invention of stereotype printing by Charles Earl Stanhope, the discovery of vaccination by Jenner, the introduction of gas into general use by Murdoch, and the construction, in a great measure, of the present system of canal communication by Jessop, Chapman, Telford, and Rennie.

During the same period of time were likewise living Count Rumford, Robert Brown, the botanist, William Smith, the father of English geology, Thomas Young, the natural philosopher, Brunel, Bentham, Maudsley, and Francis Ronalds, who by securing perfect insulation was the first to demonstrate the practicability of passing an electric message through a lengthened space, together with many others, the fruits of whose labors we are now reaping.

The following pages briefly record the births, deaths, and more striking incidents in the lives of those benefactors to mankind.

Lives of great men all remind us we may make our lives sublime.

giving in a letter to his friend Mr. Davies Gilbert, dated April the 16th, 1799, the first intimation of the intoxicating qualities of that gas.

Shortly afterwards he examined its properties more accurately, administering it to various individuals, and published an account of his discoveries in a volume entitled Researches Chemical and Philosophical Chiefly Concerning Nitrous Oxide and its Respiration.

While the favourable impression from this publication was still fresh on the public mind, the establishment of the Royal Institution, under the auspices of Count Rumford, had taken place, and a lecturer of talent was wanting to fill the chemical chair.

Through the recommendation of Dr.

It was at this juncture that the Amazonian dames mentioned in the poem became so frightened at the prospect that they resolved to fortify Boston Neck.

Dux Femina Facti March 1676 A grand attempt some Amazonian dames Contrive whereby to glorify their names A rough for Boston Neck of mud and turf Reaching from side to side, from surf to surf Their nimble hands spin up like Christmas pines Their pastry by degrees on high doth rise The wheel at home counts it an holiday Since while the mistress worketh it may play A tribe of female hands, but manly hearts Forsake at home their pastry crust and tarts To knead the dirt the samplers down they hurl Their undulating silks they closely furl The pickaxe one as a commandress holds While t'other at her aukness gently scolds One puffs and sweats the other mutters why Can't you promote your work so fast as I Some dig, some delve, and the other's hands do feel The little wagon's weight with single wheel And least some feigning fits the weak surprise They want no sacks nor cakes, they are more wise These brave essays draw forth male stronger hands More like to daubers than to martial bands These do the work the sturdy bulwarks raise But the beginners well deserve the praise Benjamin Thompson End of section 26 Section 27 Of Poems of American History The Colonial Era This is a LibriVox recording All LibriVox recordings are in the public domain For more information or to volunteer please visit LibriVox.org Recorded by Chris Pyle Poems of American History The Colonial Era Chapter 7 King Philip's War and the Witchcraft Delusion Part 2 On April 21st an attack was made on Sudbury A portion of the town was burned And a relief party of over fifty which hurried up Was lured into an ambush and all but annihilated The Indians in this battle were bolder than they had ever been before And their strategy was unusually effective The Sudbury Fight April 21st 1676 Ye sons of Massachusetts All who love that honored name Ye children of New England Holding dear your father's fame Hear tell of Sudbury's battle Through a day of death and flame The painted Wampanoags Philip's hateful warriors Creep upon the town at spring tide While the skies deny us rain We see their shadows lurking In the forest whispering deep And speed the sorry tidings Past dry field and rustling lane Come hastily or never When the wild beasts lust for gore And send your best and bravest If you wish to see us more The commonwealth is quiet now And peace her measure fills Content in homes and farmsteads Busy marts and buzzing mills From the Atlantic's roaring To the tranquil Berkshire hills And through that day our fathers Speaking low their breathless words Their wives and babes in safety Toil to save their little all They fetch their slender food-stores, drive indoors their scanty herds.
