Subject: what is wrong and how to write it shorter?

#!/usr/bin/ruby
require 'net/http'
h = Net::HTTP::new('www.rubyist.net')
(1..9).each do |pages|
     pg = '/~matz/slides/oscon2005/mgp0000' + pages + '.txt'
     resp, data = h.get(pg)
     print data, "\n"
     puts 10 * '-'
end

(10..59).each do |pages_2|
     pg = '/~matz/slides/oscon2005/mgp000' + pages_2 + '.txt'
     resp, data = h.get(pg)
     print data, "\n"
     puts 10 * '-'
end

An attempt to write it shorter
#!/usr/bin/ruby
require 'net/http'
h = Net::HTTP::new('www.rubyist.net')
h.get('/~matz/slides/oscon2005/') { |pages|
     print pages, "\n"
     puts 10 * '-'
}
in theory, above code merge html and text. How to pick up text only file?
