"$variable" is not behaving as a string in my script

Hi All,
I am using the below while syntax for reading my file but its not working. Below is the line in my file
" 123 rteyu 566"
when I use below code the spaces are truncated for 1st variable
while read line
do
x=`echo "$line"|cut -c 1-8`
y=`echo "$line"|cut -c 9-15`
echo "$x"
echo "$y"
done < file

Ideally x should show " 1" and y should be "23 r"
But x is showing value "123 r".
The intial spacing is being trucated.
Can any one help me on this!!!!!!
