"In my last I contended that none of those ties which are necessary to bind a people together and make them one, existed between the colonists and Mexicans"

This quote by William H. Wharton is describing the absence of unity between the colonists and Mexicans. He is suggesting that the two groups are not connected in any meaningful method, which there is no sense of shared identity or function between them. This absence of unity is most likely due to the fact that the colonists are from a different culture and have different values and beliefs than the Mexicans. This lack of unity has likely caused tension between the two groups, as they are not able to come together and work towards a typical goal. This quote is a suggestion that in order for a people to be merged, there should be a strong sense of connection and understanding between them. Without this, it is hard for them to come together and work towards a typical goal.
