arduino and processing serial communication proble

Hi,
I expect integers from 0 to 360 (degrees) comming from arduino to processing, but processing gives me a chaos, consisting 49, 49, 51, 48...unexpected!

Arduino, generates integers:

long angle = 0;
void setup()
{
Serial.begin(9600);
}

void loop()
{
Serial.println(angle);
angle += 1;
if(angle>=360)
angle = 0;
}

Processing, reads the serial port:

import processing.serial.*;
int angle=0;
Serial port;
void setup() 
{
port = new Serial(this, "COM4", 9600);
}

void draw() 
{
if(port.available() > 0)
{
println(port.read());
}
}

where am I wrong? (COM4 is the right port on both)

49, 49, 51, 48

Those are the ASCII codes for '1', '1', '3', '0'. I don't know enough Processing to help with that end of it, though!

well I was not sending ascii, but long, then should I convert always to ascii for transferring serially?
