Passage 1:Following the war, Walker served on the editorial staff of the Springfield Republican before using his family and military connections to gain appointment as the Chief of the Bureau of Statistics from 1869 to 1870 and Superintendent of the 1870 census where he published an award-winning Statistical Atlas visualizing the data for the first time. He joined Yale University's Sheffield Scientific School as a professor of political economy in 1872 and rose to international prominence serving as a chief member of the 1876 Philadelphia Exposition, American representative to the 1878 International Monetary Conference, President of the American Statistical Association in 1882, and inaugural President of the American Economic Association in 1886, and vice president of the National Academy of Sciences in 1890. Walker also led the 1880 census which resulted in a twenty-two volume census, cementing Walker's reputation as the nation's preeminent statistician.
 Passage 2:Louiche Mayorga played with Suicidal Tendencies from 1981 to 1988 and Los Cycos from 1984 to 1985. In 1983 he played on the self-titled "Suicidal Tendencies album" on Lisa Fancher's, Frontier Records and co-wrote four of the songs, "Two Sided Politics," "Won't Fall in Love Today," "Memories of Tomorrow" (which was covered by Slayer for their album Undisputed Attitude, but was not added to the final release) and the punk classic "Institutionalized" (which was covered by Senses Fail for the soundtrack to the video game Tony Hawk's American Wasteland ). You can also hear his voice on the answer call vocal in the opening track "Suicides an Alternative/ You'll Be Sorry." His second recording was on Suicidal Records (a label he co-founded with vocalist Mike Muir) for the "Welcome to Venice" compilation. Mayorga played on two cuts "Look Up...(The Boys Are Back) with Suicidal Tendencies, and the song "It's Not Easy" with "Los Cycos." His third in 1987 being the highly anticipated "Join the Army" on Caroline Records where he co-wrote the title track "Join the Army," and six others "The Prisoner," "War Inside My Head," (which is also featured in the game .) "Possessed to Skate" (Which is featured in the game Skate 2, "No Name, No Words," "Looking in Your Eyes" and "Born to Be Cyco" which he shares credit with Rocky George and Mike Muir.

Herrera (drums), Amery Smith (drums), Sal Troy (drums), Grant Estes (lead guitar), Jon Nelson (lead guitar) and Rocky George (lead guitar). At the end of 1988, Louiche was asked to leave Suicidal and told that "his playing had gotten worse" and that "he wasn't good anymore." Muir allegedly withheld Mayorga's part of the royalty payments. In an interview Louiche stated "It was around $100,000 dollars and I had to sue him (Mike Muir) to get my money back." When Mike Muir switched Suicidal's musical style from punk to metal, he was replaced by ex-No Mercy bassist Ric "Rancid" Clayton (the artist who designed the Suicidal Tendencies logo as well as the shirts on S.T.'s first album), but he was quickly replaced by Bob Heathcote.
