Gazette and Daily Advertiser called "the beautiful and most brilliant light". The following year, a group of investors formed the Gas Light Company of Baltimore, which was authorized by the municipal government to lay pipes to use coal gas to light public streets. Although both New York and Philadelphia experimented with gas street lighting around this time, the sophistication of their existing oil-based lighting systems meant that those cities were slower to replace the street lamps they already had with technology that was still unproven. By 1835, New York, Philadelphia, and Boston had also built the requisite infrastructure of piped networks connected to manufacturing gas plants (MGPs) to supply gas light to shopping boulevards, wealthy residential neighborhoods, and major thoroughfares. That year, only 384 of New York City's 5,660 street lamps were gaslights. Chicago turned on its first hundred-odd gaslights on September 4, 1850. Gas light was up to ten times brighter than light from oil lamps, but by present-day standards, the lights appeared "distinctly yellow and not very bright". In 1841, British author James Silk Buckingham observed that New York City's street lights were inadequate: “The lamps are so far apart and so scantily supplied with light that it is impossible to distinguish names or numbers on the doors from carriages or even on foot without ascending the steps." By 1893, New York City had 26,500 gas street lights and only 1,500 electrical lights. Electric street lighting Arc lamps The first public demonstration of outdoor electrical lighting in the US was in Cleveland, Ohio, on April 29, 1879. Inventor Charles F. Brush had been perfecting the dynamo arc light, which could produce a glow equivalent to 4,000 candles in a single lamp. For the demonstration, which drew a crowd of thousands, Brush positioned twelve 2,000-candlepower lamps on towers around Cleveland's Public Square (then known as Monumental Park), and fully illuminated it with electric light. The first municipal government to purchase and install the Brush arc lighting system was the city of Wabash, Indiana. On March 31, 1880, Wabash became "the first town in the world generally lighted by electricity," as four 3,000-candlepower Brush lights suspended from the flagstaff on top of the Wabash County Courthouse were switched on, flooding the neighborhood with light. According to an eyewitness, "The people, almost with bated breath, stood overwhelmed with awe." The journalist reported that he had been able to read a newspaper,
