copy a line from one file to another

I like to know what unix command i can use to append the second line of file #1 to the end of file #2 so that it performs the following. Thanks in advance. The purpose of this is to keep track of another log file (from crontab) that i have which the log content is flushed every 5 minutes so that i need to keep copying the content when it is ready before it is flushed. Thanks.

###BEFORE###
<file #1>
this is file #1, line 1
this is file #1, line 2

<file #2>
this is file #2

###AFTER###
<file #1>
this is file #1, line 1
this is file #1, line 2

<file #2>
this is file #2
this is file #1, line 2

The second line of file#1 is the last here but is it always the case?
Code:
 tail -1 file-1 >>file-2
