On May 30, 1922, George Hermann, a millionaire, donated land to the city that would later become the Hermann Park. September of the same year saw the start of the Houston Zoo. The zoo was started when Houston schoolchildren bought two ostriches. The zoo was later moved from Sam Houston Park to Hermann Park. September 26 saw the first international-bound ship in the port. During the Roaring Twenties, more specifically 1927, the state highway to Houston was built. Bus and truck operations also fell into swing. Houston Junior College opened its doors that same year, which would later become the University of Houston. August 1929 saw the first Sears into Houston. Then Black Tuesday threw devastating blow to the economy of the entire United States. Houston's growth was much smaller, but the city still grew. Mexican Americans no longer saw easy to obtain jobs, yet several were successful by catering to the Caucasian market in the city.
