Use security software that updates automatically

Keep your security software active and current: at a minimum, your computer should have anti-virus and anti-spyware software, and a firewall. You can buy stand-alone programs for each element or a security suite that includes these programs from a variety of sources, including commercial vendors or from your Internet Service Provider. Security software that comes pre-installed on a computer generally works for a short time unless you pay a subscription fee to keep it in effect. In any case, security software protects against the newest threats only if it is up-to-date. That's why it is critical to set your security software to update automatically.

Some scam artists distribute malware disguised as anti-spyware software. Resist buying software in response to unexpected pop-up messages or emails, especially ads that claim to have scanned your computer and detected malware. That's a tactic scammers have used to spread malware. OnGuardOnline.gov can connect you to a list of security tools from legitimate security vendors selected by GetNetWise, a project of the Internet Education Foundation.

Once you confirm that your security software is up-to-date, run it to scan your computer for viruses and spyware. If the program identifies a file as a problem, delete it.

Keys To Use

Never leave a spare key in a convenient hiding place such as under the doormat, in a flowerpot or behind a loose brick - thieves know all the usual hiding places.

If you move into a new home, change the front and back door locks immediately – other people may have keys that fit. Look in your phone book for the names of local locksmiths who are members of the Master Locksmiths’ Association.

Never leave your house or car keys in or near a door or window. Some thieves have been known to use a fishing rod or magnet on a stick to steal them through the letterbox.

Decide on a safe place for your keys and always use it, so you can find them in an emergency.

Increasingly, burglars are breaking in to steal the keys of high-value cars. So take care of your keys and, if you have a garage, keep your car in it rather than on the drive.

Alternative Fuel Vehicles

Alternative Fuel Vehicles are designed to improve air quality and the environment by lowering or eliminating ozone-forming tailpipe emissions. GSA owns more AFVs than any single organization in the United States. We anticipate selling approximately 4,000 AFVs in the coming year, including sedans, pickups, buses, vans, delivery trucks and specialty vehicles.

Alternative fuels include compressed natural gas, propane, hydrogen, and gasoline blends containing up to 85% alcohol (methanol or denatured ethanol). Currently, three main types
of vehicles operating on alternative fuels are available:

  • Flexible Fuel Vehicles contain a single fuel tank capable of operating on alcohol, gasoline or a combination of both (gasohol).
  • Bi-Fuel Vehicles have two fuel systems, allowing the driver to switch between gasoline and compressed natural gas or propane.
  • Dedicated Fuel Vehicles can only run on a single alternative fuel source.

In addition to environmental benefits, Alternative Fuel Vehicles offer owners numerous advantages. Many states permit AFVs to drive in HOV lanes and offer tax rebates on AFV purchases. GSA also provides matching funds to agencies participating in the
Federal Government's AFV User Program.

Cold Water Fishing

Featured species in the cold water fisheries of the Finger Lakes include brown trout, rainbow trout, Atlantic salmon, and lake trout. Lake trout is the "bread and butter" species in most of the lakes' coldwater fisheries and may be caught in Skaneateles, Owasco, Cayuga, Seneca, Keuka, Canandaigua, Canadice and Hemlock Lakes. Skaneateles and Keuka Lakes host natural reproducing lake trout. Rainbow trout are very abundant in Skaneateles lake, and also available in Owasco, Cayuga, Seneca, Keuka, Canandaigua, Canadice, and Hemlock Lakes. Although elusive in many of the lake fisheries, they avail themselves to anglers during the spring tributary fishing in Naples Creek, Catharine Creek, Grout Brook, Cayuga Inlet, Owasco Inlet, Cold Brook Stream (Keuka Lake Inlet), and Springwater Creek. Rainbow trout have become naturalized in Cayuga, Skaneateles, Owasco, Seneca, Keuka Hemlock, and Canandaigua Lakes with natural reproduction supplemented by stocking. Brown trout can be found in all the Finger Lakes except Conesus and Honeoye Lakes. Try shore fishing or surface trolling in the spring for browns. Atlantic salmon can be found in Skaneateles, Cayuga, Seneca, Keuka, and Hemlock Lakes.

Conflict with vehicles by Kangaroo


A collision with a vehicle is capable of killing a kangaroo. Kangaroos dazzled by headlights or startled by engine noise have been known to leap in front of cars. Since kangaroos in mid-bound can reach speeds of around 50 km/h (31 mph) and are relatively heavy, the force of impact can be severe. Small vehicles may be destroyed, while larger vehicles may suffer engine damage. The risk of harm to vehicle occupants is greatly increased if the windscreen is the point of impact. As a result, "kangaroo crossing" signs are commonplace in Australia.

Vehicles that frequent isolated roads, where roadside assistance may be scarce, are often fitted with "roo bars" to minimal damage caused by collision. Bonnet-mounted devices, designed to scare wildlife off the road with ultrasound and other methods, have been devised and marketed.

If a female is the victim of a collision, animal welfare groups ask that her pouch be checked for any surviving joey, in which case it may be removed to a wildlife sanctuary or veterinary surgeon for rehabilitation. Likewise, when an adult kangaroo is injured in a collision, a vet, the RSPCA or the National Parks and Wildlife Service can be consulted for instructions on proper care. In New South Wales, rehabilitation of kangaroos is carried out by volunteers from WIRES.

Types of Photographs

Types of Photographs

A photographic image is formed by the action of light falling onto a base material which has been coated with a light-sensitive emulsion. This latent image may then be "developed" and "fixed" by further chemical processing. The emulsion coating in most modern photographs is usually gelatin, which incorporates either silver halide salsts to form black and white images, or dyes or pigments to form colour images. The base can be made from any material that can be coated with an emulsion, but the most common bases are paper and film.

  • Paper based prints-either color or black and white with a variety of emulsion types, depending on the age of the material. These can be simple "snapshots" to mounted presentation photographs to very large aerial survey shots.
  • Negatives-reversed polarity images from which positive prints are produced which can be colour or black and white, and in a range of sizes. Early negatives were on glass, but for most of the twentieth century, flexible film bases have been used. Film-based negatives can be in either sheet or roll form.
  • Transparencies or slides-positive images on a transparent film base, therefore requiring viewing with a back light source or projection system. The most common are 35mm slides, but other sizes are also used.

History of the Treasury Building


In the first years of the American republic's existence, the federal government was located in Philadelphia, Pennsylvania. In 1800, the federal government moved to Washington, DC and the Department of the Treasury moved into a porticoed Gregorian-style building designed by an English architect, George Hadfield.

This structure was partially destroyed by fire in 1801. Later it was burned by the British in 1814, but was rebuilt by White House architect James Hoban. This building was identical to three others located on lots adjacent to the White House, each housing one of the first four departments of the U.S. Government: the State Department, the War Department, the Navy Department, and the Treasury Department. The Treasury Building, to the southeast of the White House, was again burned by arsonists on March 31, 1833, with only the fireproof wing left standing.

The three years after the 1833 fire that destroyed the second Treasury Building, the Department was without a home of its own. On July 4, 1836, Congress authorized the construction of a "fireproof building of such dimensions as may be required for the present and future accommodations" of the Treasury Department.

This legislation authorized the East and Center Wings. They were partially occupied in August 1839 and were completed in 1842. They were designed by Robert Mills, who was also the architect of the Washington Monument and the Patent Office Building. The most architecturally impressive feature of the Mills design is the east front colonnade running the length of the building.

Each of the 30 columns is 36 feet tall and was carved out of a single block of granite. The material for the original Wing was Acquia Creek freestone, which was largely replaced with granite in 1908. The interior design of the east and center wings is classically austere, in keeping with the Greek Revival style. Perhaps the building when completed in 1842 was an imposing structure for the time, but it fell short of providing accommodations for the future. Having cost less than $700,000, the building, which is now only a part of the east wing, contained 150 rooms.

It was found necessary in a few years to enlarge the building, and on March 3, 1855, Congress granted authority to extend the building, by appropriating $100,000. Construction of what is now the South Wing was begun in July 1855 and completed and occupied in September 1861. Construction started on the west wing in 1855 and was completed and occupied in 1864. The preliminary design of the wings was provided by Thomas Ustick Walter, architect of the dome of the U.S. Capitol, but construction began under the supervision of Ammi B. Young and from 1862 until 1867 by Isaiah Rogers. They each refined the plans, designed the interior details. While the exterior of the building was executed along the lines of the original Mills wings, the interiors of the later wings reflect changes in both building technology and aesthetic tastes. Iron columns and beams reinforced the building's brick vaults, and the architectural detailing became much more ornate, following mid-nineteenth century fashion.

The Department continued to grow, and construction began on the North Wing, the final addition to the Treasury Building in 1867. The Government building housing the Department of State was removed from the north area of the site in 1866-67 to make room for the North Wing.The architect of the North Wing was Alfred B. Mullett, who subsequently designed the Old Executive Office Building, which originally housed the State Department, the War Department and the Navy Department.

The north wing of the Treasury Building contains the Cash Room -- a two-story marble hall in which the daily financial business of the U.S. Government was transacted. The room was opened in 1869 as the site of President Ulysses S. Grant's Inaugural Ball. This wing was completed in 1869. The Attic story, now the Treasury Building's fifth floor, was added in 1910.

The stone used in the South Wing, the West Wing and the North Wing, was quarried on Dix Island, near Rockland, Maine, and transported in sailing vessels. The facades are adorned by monolithic columns of the Ionic order, each 36 feet tall and weighing 30 tons. Each column cost $5,000.

There are 34 of these pillars on the east side of the building facing Fifteenth Street, 30 of them forming a colonnade 341 feet long. This colonnade has for many years provided viewing space for inaugural parades and other state functions. There are 18 columns on the west side and ten each on the north and south sides.

Thus, after more than a third of a century, the Treasury Building became the magnificent structure originally intended. One of the results of its expansion, though, was the violation of the original plan for the city -- to leave unobstructed the view from the White House to the Capitol.

The building as it is today is estimated to have cost approximately $8 million. Early planning had the entire capital city facing the Washington Canal which at one time ran through downtown Washington where the National Mall is now located. Because of its location, the south entrances of the Treasury Building, along with the south entrance of the White House, is the historical front entrance of the building.

The Treasury Building is the oldest departmental building in Washington, and the third oldest federally occupied building in Washington, preceded only by the Capitol and the White House. The Main Treasury Building covers five stories and a raised basement and sits on 5 acres of ground. The building measures 466 feet north to south by 260 feet east to west.

A Statue of Alexander Hamilton, the 1st Secretary of the Treasury, is located on the south patio of the building, while a statue of Albert Gallatin, the 4th Secretary of the Treasury, is located on the north patio. Gallatin served the longest as Secretary, from 1801 until 1814. The grounds of the building -- rose gardens at the north and south ends and grass, magnolia trees and other plantings gracing the west side -- add much to the beauty of the building.

The Main Treasury Building has had a great impact on the design of other government buildings. At the time of its completion, it was one of the largest office buildings in the world. It is unquestionably a monument of continuing architectural and historic significance. The Treasury Building was dedicated as a National Historic Landmark on October 18, 1972.
