h is a nested hash. When you do h['return'] you get another hash:

2.0.0p195 :006 >   h['return']
 => {"29777582"=>{"pair"=>"ltc_rur", "type"=>"sell", "amount"=>1.0,
"rate"=>88.99999, "timestamp_created"=>1375718423, "status"=>0},
"29777557"=>{"pair"=>"ltc_rur", "type"=>"sell", "amount"=>1.0,
"rate"=>89.0, "timestamp_created"=>1375718410, "status"=>0},
"29777530"=>{"pair"=>"ltc_rur", "type"=>"sell", "amount"=>0.27066199,
"rate"=>90.0, "timestamp_created"=>1375718389, "status"=>0}}

h['return']['29777582'] will return yet another hash, the one assigned
to the key 29777582:

2.0.0p195 :007 > h['return']['29777582']
 => {"pair"=>"ltc_rur", "type"=>"sell", "amount"=>1.0,
"rate"=>88.99999, "timestamp_created"=>1375718423, "status"=>0}

and so on. You should read some tutorial or documentation about
hashes, in order to better understand this structure. If you want to
iterate over all the elements inside 'return' you can use the #each
method:

h['return'].each do |key, value|
  puts "key #{key} has the following value assigned: #{value.inspect}"
end

Hope this helps,

Jesus.
