Food for or, at the option of the person entering the copyright, the words, "Copyright 



Plants iQ — ^ by ." The law imposes a penalty of ^lOO upon any person who 



has not obtained copyright who shall insert the notice, " Entered according to 

 act of Congress," or "Copyright," or words of the same import, in or upon 

 any book or other article. Each copyright secures the exclusive right of 

 publishing the book or article copyrighted for the term of twenty-eight years. 

 Six months before the end of that time, the author or designer, or his widow 

 or children, may secure a renewal for the further term of fourteen years, mak- 

 ing forty-two years in all. Any copyright is assignable in law by any instru- 

 ment of writing, but such assignment must be recorded in the office of the 

 Librarian of Congress within sixty days from its date. The fee for this 

 record and certificate is one dollar. A copy of the record (or duplicate 

 certificate) of any copyright entry will be furnished, under seal, at the rate of 

 50 cents. Copyrights cannot be granted upon trade-marks, nor upon labels 

 intended to be used with any article of manufacture. If protection for such 

 prints or labels is desired, application must be made to the Patent Office, 

 where they are registered at a fee of $6 for labels and $25 for trade-marks. 

 An American author, who is within the British dominions at the time of the 

 first publishing of his book, and who publishes it there, is entitled to the 

 protection of their copyright laws.

1. A sewing-machine does the work of 12 women. The United States 

 export 100,000 of these machines yearly. 



2. A Boston "bootmaker" will enable a workman to make 300 pairs of 

 boots daily. In 1880 there were 3,100 of these machines in various coun- 

 tries, turning out 150 million pairs of boots yearly. 



3. Glenn's California reaper will cut, thresh, winnow and put in bags 

 the wheat of 60 acres in 24 hours. 



4. The Hercules ditcher, Michigan, removes 750 cubic yards, or 700 

 tons of clay per hour. 



5. The Darlington borer enables one man to do the work of seven in 

 making a tunnel, and reduces the cost to one-third of work done by hand; it 

 also permits a week's work to be done in two days.
