In the 19th century, and indeed well into the 20th century, when paper was less readily available, individual students also wrote with chalk on their own small slates . Both pencils and chalk exist in variants which can create marks in other colors, but colored pencils and colored chalk are generally considered to be art supplies rather than writing instruments. Similarly, although very young children may use colorful wax crayons to write words into their pictures, writing
8960-401: The ink from evaporating dry or wicking into the user's pocket. Depending on the design of the pen, the ink reservoir can be filled in several different ways: direct addition by eyedropper, suction from an internal mechanism, or disposable pre-filled cartridges. Some cartridge-based fountain pens can be fitted with "converters", which are separate piston/suction reservoirs of the same dimensions as
9072-428: The ink to leak when travelling by airplane. A large number of new pen types were popularized in the 20th century. Some of them are not constructed to be refilled with ink after they run dry; although others can theoretically have their internal ink compartment replaced, the widespread custom is to simply throw away the entire pen when its ink is no longer accessible. These types include the ballpoint pen (often called
9184-463: The integration of Army National Guard units and personnel into the U.S. Army and (since 1947) the U.S. Air Force. There are about 18,000 U.S. police agencies from local to national level in the United States. Law in the United States is mainly enforced by local police departments and sheriff departments in their municipal or county jurisdictions. The state police departments have authority in their respective state , and federal agencies such as
9296-482: The military draft (leading to the end of conscription in 1973) and wide opposition to U.S. intervention in Vietnam (with the U.S. totally withdrawing in 1975). A societal shift in the roles of women was significantly responsible for the large increase in female paid labor participation during the 1970s, and by 1985 the majority of American women aged 16 and older were employed. The late 1980s and early 1990s saw
9408-612: The most attractive to the population are the most vulnerable. The U.S. is one of 17 megadiverse countries containing large numbers of endemic species : about 17,000 species of vascular plants occur in the contiguous United States and Alaska, and over 1,800 species of flowering plants are found in Hawaii, few of which occur on the mainland. The United States is home to 428 mammal species, 784 birds, 311 reptiles, 295 amphibians , and around 91,000 insect species. There are 63 national parks , and hundreds of other federally managed parks, forests, and wilderness areas , managed by
9520-662: The most violent, the California genocide of thousands of Native inhabitants, lasted into the early 1870s, just as additional western territories and states were created.

States in the North enacted abolition laws , though support for slavery strengthened in Southern states , as inventions such as
9632-496: The page. The print may be inked or blind, but is typically done in a single color. Motifs or designs may be added as many letterpress machines use movable plates that must be hand-set. Letterpress printing remained the primary method of printing until the 19th century. When a single document needs to be produced, it may be handwritten or printed, typically by a computer printer. Several copies of one original paper can be produced by some printers using multipart stationery . Typing with
9744-985: The paper and covered in ink. Due to the cost of the process and expertise required, many consumers opt for thermographic printing, a process that results in a similarly raised print surface, but through different means at less cost. Many shops that sell stationery also sell other school supplies for students in primary and secondary education, including pocket calculators , display boards , compasses and protractors , set squares, lunch boxes, and related items. This section contains an incomplete list of famous brands, manufacturers and retailers of stationery worldwide. In US and Canada , Office Depot and Staples are two major retailers of stationery. Notable stationery brands in Europe include LAMY , MOLESKINE , Staedtler , and Faber-Castell . In Japan, major manufacturers of stationery include Kokuyo, Maruman, Lihit Lab, King Jim, MUJI and Tombow. MUJI also has about 800 retail stores worldwide. In mainland China, 晨光文具 (Chén guāng wén jù)
9856-401: The paper into a shape that can be observed on both the front and back surfaces. Two things are required during the process of embossing: a die and a stock. The result is a three-dimensional (3D) effect that emphasizes a particular area of the design. Engraving is a process that requires a design to be cut into a plate made of relatively hard material. The metal plate is first polished so that
9968-431: The pen's usual refill cartridge; these allow the pen to refill from bottled ink. Only certain types of ink can be used in a fountain pen, to avoid clogging up the nib unit mechanism. Although the larger reservoir of fountain pens requires less frequent ink replenishment, the ink may inconveniently spill out in certain contexts to stain the paper, fingers, or clothing of an unwary writer. Differences in air pressure may cause
10080-434: The pen-holder can accommodate a wide variety of nibs that are specialized for different purposes: copperplate writing, mapping pens, and five-pointed nibs for drawing music staves . They can be used with most types of ink, some of which are incompatible with other types of pen. Automatic pens are a category of dip pen, in which the nib is in two parts and can hold a larger quantity of ink. However, like all of its precursors,
10192-408: The policy of redlining later adopted by the federal Home Owners' Loan Corporation . An explosion of technological advancement accompanied by the exploitation of cheap immigrant labor led to rapid economic expansion during the late 19th and early 20th centuries , allowing the United States to outpace the economies of England, France, and Germany combined. This fostered the amassing of power by
10304-472: The position of the graphite by friction, so that although it remains steady while writing, the graphite can be advanced forward to compensate for gradual wear or retracted to protect it when not in use. The graphite in mechanical pencils is typically much narrower than in wooden pencils, frequently in sub-millimeter diameters. This makes them particularly useful for fine diagrams or small handwriting, although different sizes of refill leads cannot be interchanged in
10416-574: The primary colonial grievances was a denial of their rights as Englishmen , particularly the right to representation in the British government that taxed them . To demonstrate their dissatisfaction and resolve, the First Continental Congress met in 1774 and passed the Continental Association , a colonial boycott of British goods that proved effective.

In the northwest corner of Arizona , carved by the Colorado River over millions of years, is the Grand Canyon , a steep-sided canyon and popular tourist destination known for its overwhelming visual size and intricate, colorful landscape. The Sierra Nevada and Cascade mountain ranges run close to the Pacific coast . The lowest and highest points in
10864-459: The same pencil unless it has been specially designed for that purpose. Although in Western civilization writing is usually done with some form of pencil or pen , other cultures have used other instruments. Chinese characters are traditionally written with a brush , which is perceived as lending itself to a graceful, flowing stroke. A brush differs from a pen in that instead of a rigid nib,
10976-573: The six service branches, which are made up of the U.S. Army , Marine Corps , Navy , Air Force , and Space Force . The Coast Guard is administered by the Department of Homeland Security in peacetime and can be transferred to the Department of the Navy in wartime.

11088-545: The sole authority of a state government. SDFs are authorized by state and federal law but are under the command of the state's governor . They are distinct from the state's National Guard units in that they cannot become federalized entities. A state's National Guard personnel, however, may be federalized under the National Defense Act Amendments of 1933 , which created the Guard and provides for

The United States has an established structure of foreign relations, and it has
11312-412: The steel-nibbed dip pens had a limited ink reservoir and a tendency to drip inkblots on the page. The first modern fountain pens were developed in the 19th century, with functionally similar designs appearing as early as the 10th century. These consist of the nib unit, an ink reservoir chamber, and an external casing. The casing usually includes a cover for the nib, in order to protect its shape and keep
11424-510: The structure and responsibilities of the national federal government and its relationship with the individual states. The U.S. Constitution is the world's oldest national constitution still in effect (from March 4, 1789). Composed of three branches, all headquartered in Washington, D.C., the federal government is the national government of the United States. It is regulated by a strong system of checks and balances . The three-branch system
11536-407: The surface. The concept has been revived in recent times as the core of the inkless pen : a lead-based metal alloy that leaves dark markings on paper by abrading small pieces of core onto the surface. However, most modern "lead pencils " have a nonpoisonous core of greyish-black graphite mixed with various proportions of clay for consistency, enclosed within an outer wooden casing to protect
11648-582: The world's fourth-longest river system , runs predominantly north–south through the heart of the country. The flat and fertile prairie of the Great Plains stretches to the west, interrupted by a highland region in the southeast.

In the American Southwest , droughts became more persistent and more severe. The regions considered as
12208-575: Was annexed in 1845, and the 1846 Oregon Treaty led to U.S. control of the present-day American Northwest . Victory in the Mexican–American War resulted in the 1848 Mexican Cession of California, Nevada, Utah, and much of present-day Colorado and the American Southwest . The California gold rush of 1848–1849 spurred a huge migration of white settlers to the Pacific coast, leading to even more confrontations with Native populations. One of
12320-477: Was accidentally preserved by a catastrophic fire which hard-baked those tablets. The Romans used lead styli with wax tablets which could be "erased" by rubbing the beeswax surface smooth again. In the modern era, hand held computers and certain other computer input devices use a stylus to enter information onto a screen by applying pressure rather than by depositing pigment. Words and names are still commonly inscribed into commemorative objects, such as
